+
+   1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
+   UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
+   word product in HIGH_PROD and LOW_PROD.
+
+   2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
+   UDWtype product.  This is just a variant of umul_ppmm.
+
+   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator) divides a UDWtype, composed by the UWtype integers
+   HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
+   in QUOTIENT and the remainder in REMAINDER.  HIGH_NUMERATOR must be less
+   than DENOMINATOR for correct operation.  If, in addition, the most
+   significant bit of DENOMINATOR must be 1, then the pre-processor symbol
+   UDIV_NEEDS_NORMALIZATION is defined to 1.
+
+   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator).  Like udiv_qrnnd but the numbers are signed.  The quotient
+   is rounded towards 0.
+
+   5) count_leading_zeros(count, x) counts the number of zero-bits from the
+   msb to the first nonzero bit in the UWtype X.  This is the number of
+   steps X needs to be shifted left to set the msb.  Undefined for X == 0,
+   unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
+
+   6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
+   from the least significant end.
+
+   7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
+   high_addend_2, low_addend_2) adds two UWtype integers, composed by
+   HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
+   respectively.  The result is placed in HIGH_SUM and LOW_SUM.  Overflow
+   (i.e. carry out) is not stored anywhere, and is lost.
+
+   8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
+   high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
+   composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
+   LOW_SUBTRAHEND_2 respectively.  The result is placed in HIGH_DIFFERENCE
+   and LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
+   and is lost.

-/*************************************************************************
- * Exception Vector Table
- *
- * This could have gone in the cpu soure tree, but the whole point of
- * Nios is customization -- and polluting the cpu source tree with
- * board-specific ifdef's really defeats the purpose, no? With this in
- * the board-specific tree, each board has the freedom to organize
- * vectors/traps, etc anyway it wants. The init code copies this table
- * to the proper location.
- *
- * Each board can do what it likes here. But there are four "standard"
- * handlers availble:
- *
- *	_cwp_lolimit	-Handles register window underflows.
- *	_cwp_hilimit	-Handles register window overflows.
- *	_timebase_int	-Increments the timebase.
- *	_brkpt_hw_int	-Hardware breakpoint handler.
- *	_brkpt_sw_int	-Software breakpoint handler.
- *	_def_xhandler	-Default exception handler.
- *
- * _timebase_int handles a Nios Timer interrupt and increments the
- * timestamp used for the get_timer(), reset_timer(), etc. routines. It
- * expects the timer to be configured like the standard-32 low priority
- * timer.
- *
- * _def_xhandler dispatches exceptions/traps via the external_interrupt()
- * routine. This lets you use the irq_install_handler() and handle your
- * interrupts/traps with code written in C.

-/*************************************************************************
- * Exception Vector Table
- *
- * This could have gone in the cpu soure tree, but the whole point of
- * Nios is customization -- and polluting the cpu source tree with
- * board-specific ifdef's really defeats the purpose, no? With this in
- * the board-specific tree, each board has the freedom to organize
- * vectors/traps, etc anyway it wants. The init code copies this table
- * to the proper location.
- *
- * Each board can do what it likes here. But there are four "standard"
- * handlers availble:
- *
- *	_cwp_lolimit	-Handles register window underflows.
- *	_cwp_hilimit	-Handles register window overflows.
- *	_timebase_int	-Increments the timebase.
- *	_def_xhandler	-Default exception handler.
- *
- * _timebase_int handles a Nios Timer interrupt and increments the
- * timestamp used for the get_timer(), reset_timer(), etc. routines. It
- * expects the timer to be configured like the standard-32 low priority
- * timer.
- *
- * _def_xhandler dispatches exceptions/traps via the external_interrupt()
- * routine. This lets you use the irq_install_handler() and handle your
- * interrupts/traps with code written in C.

-/*************************************************************************
- * Exception Vector Table
- *
- * This could have gone in the cpu soure tree, but the whole point of
- * Nios is customization -- and polluting the cpu source tree with
- * board-specific ifdef's really defeats the purpose, no? With this in
- * the board-specific tree, each board has the freedom to organize
- * vectors/traps, etc anyway it wants. The init code copies this table
- * to the proper location.
- *
- * Each board can do what it likes here. But there are four "standard"
- * handlers availble:
- *
- *	_cwp_lolimit	-Handles register window underflows.
- *	_cwp_hilimit	-Handles register window overflows.
- *	_timebase_int	-Increments the timebase.
- *	_def_xhandler	-Default exception handler.
- *
- * _timebase_int handles a Nios Timer interrupt and increments the
- * timestamp used for the get_timer(), reset_timer(), etc. routines. It
- * expects the timer to be configured like the standard-32 low priority
- * timer.
- *
- * _def_xhandler dispatches exceptions/traps via the external_interrupt()
- * routine. This lets you use the irq_install_handler() and handle your
- * interrupts/traps with code written in C.

-	      SSV ADNP/ESC1 Embedded Softcore Computing
-		 Nios Softcore, Altera Cyclone FPGA
-
-		    Last Update: February 27, 2004
-====================================================================
-
-This file contains information regarding U-Boot and the SSV Embedded
-Nios Softcore Computing platform ADNP/ESC1. For general Nios
-information see doc/README.nios.
-
-Most stuff of this file was borrowed and based on README.dk1s10,
-the Altera DK-1S10 related information file.
-
-For those interested in contributing ... see HELP WANTED section
-in doc/README.nios.
-
-Contents:
-
-	1. Files
-	2. Memory Organization
-	3. CPU Variations
-	4. Examples
-	5. Programming U-Boot into FLASH with GERMS
-	6. Autoboot
-	7. U-Boot environment convention and update philosophy
-
-====================================================================
-
-1. Files
-=========
-	board/ssv/adnpesc1/*
-	include/configs/ADNPESC1.h
-	include/configs/ADNPESC1_base_32.h
-
-
-2. Memory Organization
-=======================
-
-For the most part, you can put things pretty much anywhere.
-This is pretty flexible for Nios. So here we make some arbitrary
-choices & assume that the monitor is placed at the end of a memory
-resource. So you must make sure TEXT_BASE is chosen appropriately.
-This is very important if you plan to move your memory to another
-place as configured at this time!
-
-	-The heap is placed below the monitor (U-Boot code).
-	-Global data is placed below the heap.
-	-The stack is placed below global data (&grows down).
-
-(see doc/README.adnpesc1_base32 too)
-
-
-3. CPU Variations
-=================
-
-There are more than one NIOS CPU variation for the ADNP/ESC1 possible.
-U-Boot supports the following CPU configurations:
-
-	- SSV Basis 32 (make ADNPESC1_base_32_config)
-	- SSV Basis 32 at DNP evaluation base board 2
-	  (make ADNPESC1_DNPEVA2_base_32_config)
-
-
-4. Examples
-============
-
-The hello_world example works fine. To try out you have to change
-the default load address from 0x0100_0000 to 0x0204_0000 in
-examples/Makefile (the real SDRAM for default board configuration).
-
-
-5. Programming U-Boot into FLASH with GERMS
-============================================
-
-The current version of the ADNP/ESC1 port with the default
-configuration settings occupies about 97 KBytes of flash.
-A minimal configuration occupies less than 70 KByte
-(network, SPI, POST and board command support disabled). You
-can save more memory by deactivating the Hu-Shell support and
-long command help (CONFIG_SYS_HUSH_PARSER, CONFIG_SYS_LONGHELP).
-
-To program U-Boot into the ADNP/ESC1 flash using GERMS do the
-following:
-
-1. Download U-Boot to its target run space in SDRAM:
-
-   a. Close jumper RCM_EN# and push the reset button.
-
-   b. From the command line, download U-Boot using the
-      nios-run:
-
-	$ nios-run -r u-boot.srec
-
-      NOTE: In some cases this want fail. I don't know why,
-	    but try again.
-
-This takes about 1 minute (GERMS is not very speedy here).
-After u-boot is downloaded it will be executed. You should
-see the following:
-
-    U-Boot 1.0.2 (Jan 30 2004 - 12:59:15)
-
-    CPU: Nios-32 Rev. 3.3 (0x3038)
-    Reg file size: 512 LO_LIMIT/HI_LIMIT: 1/30
-    Board: SSV DilNetPC ADNP/ESC1
-    Conf.: SSV Base 32 (nios_32)
-    In:    serial
-    Out:   serial
-    Err:   serial
-    ADNPESC1 >
-
-
-2. Quit nios-run and start your terminal application (e.g. start
-   Hyperterminal or minicom).
-
-3. Download the u-boot code to RAM. When using Hyperterminal, do the
-   following:
-
-   a. From the u-boot command prompt start a binary download to SDRAM:
-
-      at the SSV Basis 32 to SDRAM:
-
-	==> loadb 2000100
-
-   b. Download u-boot.bin using kermit.
-
-4. From the U-Boot command prompt, erase flash:
-
-   at the SSV Basis 32 from 0x1000000 to 0x103ffff:
-
-	==> protect off 1:0-3
-	==> erase 1:0-3
-
-5. Copy the binary image from SDRAM to flash:
-
-   at the SSV Basis 32 from SDRAM:
-
-	==> cp.b 2000100 1000000 $filesize
-
-U-Boot will now automatically start when the board is powered on or
-reset using the SSV Basis 32 configuration without closed RCM jumper.
-To start U-Boot with closed RCM Jumper, enter the following GERMS
-command:
-
-    + g 1000000
-
-
-6. Autoboot
-===========
-
-U-Boot will try to boot a valid Nios application from Flash. For this
-it will use the deposited Hu-Shell script in environment variable
-'bootcmd' which is looking for a valid Nios application identifier
-string in Flash and go on at even its entry address. For more
-information see the next chapter.
-
-
-7. U-Boot environment convention and update philosophy
-======================================================
-
-U-Boot for the SSV ADNP/ESC1 target knows about many environment
-variables used to control the startup process, update process for
-raw Nios applications, and optionally file system image updates.
-In default configuration there are two Hu-Shell scripts to update
-the Nios application and/or the file system image:
-
-1. Update Nios application (ex. the uCLinux kernel):
-
-	run 'appl_update'
-
-2. Update optional file system image (ex. RomFS image used by uCLinux):
-
-	run 'fs_update'
-
-The Nios application can be any programm code generated in relation
-to the Nios application identifier -- the string "Nios" at offset
-address 0x0c. To use the scripts like described above in a secure way
-you have to check-up the next environment variables:
-
-1. update_allowed
-
-	- Update switch -- must be set to '1' (one) to allow any update
-	- default is '0' (zero)
-
-	  NOTE:	You should avoid to save this variable with non zero
-		value to Flash. Otherwise it would be allow any
-		update process at any time!
-
-2. appl_entry_addr
-
-	- Nios application area start address (usually in Flash)
-	- this is the startup address for autoboot
-	- each Nios application code we want to update will be copied
-	  to this address
-	- default is CONFIG_SYS_ADNPESC1_NIOS_APPL_ENTRY
-
-3. appl_end_addr
-
-	- Nios application area end address (usually in Flash)
-	- will be used to unprotect/erase the Flash area while updating
-	- default is CONFIG_SYS_ADNPESC1_NIOS_APPL_END
-
-4. appl_ident_addr
-
-	- address of the Nios application identification string
-	- this is the address checked-up by autoboot
-	- default is CONFIG_SYS_ADNPESC1_NIOS_APPL_IDENT
-
-5. appl_ident_str
-
-	- the Nios application identification string itself
-	- default is CONFIG_SYS_ADNPESC1_NIOS_IDENTIFIER
-
-6. appl_name
-
-	- name of file we have to download/update
-	- default is ADNPESC1/base32/linux.bin
-
-7. fs_base_addr
-
-	- optionally file system area start address (usually in Flash)
-	- each file system we want to update will be copied to this address
-	- default is CONFIG_SYS_ADNPESC1_FILESYSTEM_BASE
-
-8. fs_end_addr
-
-	- optionally file system area end address (usually in Flash)
-	- will be used to unprotect/erase the Flash area while updating
-	- default is CONFIG_SYS_ADNPESC1_FILESYSTEM_END
-
-9. fs_name
-
-	- name of file we have to download/update
-	- default is ADNPESC1/base32/romfs.img

-
-		    Last Update: January 2, 2004
-====================================================================
-
-This file contains information regarding U-Boot and the Altera
-Nios Development Kit, Cyclone Edition (DK-1C20). For general Nios
-information see doc/README.nios.
-
-For those interested in contributing ... see HELP WANTED section
-in doc/README.nios.

-
-1. Files
-=========
-	board/altera/dk1c20/*
-	include/configs/DK1C20.h
-
-2. Memory Organization
-=======================
-
-	-The heap is placed below the monitor (U-Boot code).
-	-Global data is placed below the heap.
-	-The stack is placed below global data (&grows down).
-
-3. Examples
-============
-
-The hello_world example works fine. The default load address
-is 0x0100_0000 (the start of SDRAM).
-
-
-4. Programming U-Boot into FLASH with GERMS
-============================================
-The current version of the DK-1C20 port with the default
-configuration settings occupies about 81 KBytes of flash.
-A minimal configuration occupies less than 60 KByte (asmi
-and network support disabled).
-
-To program U-Boot into the DK-1C20 flash using GERMS do the
-following:
-
-1. From the command line, download U-Boot using the nios-run:
-
-	$ nios-run -r u-boot.srec
-
-This takes about 45 seconds (GERMS is not very speedy here).
-After u-boot is downloaded it will be executed. You should
-see the following:
-
-    U-Boot 1.0.0-pre (Oct  4 2003 - 07:39:24)
-
-    CPU: Nios-32 Rev. 3.3 (0x3038)
-    Reg file size: 256 LO_LIMIT/HI_LIMIT: 2/14
-    Board: Altera Nios 1C20 Development Kit
-    In:	   serial
-    Out:   serial
-    Err:   serial
-    ==>
-
-
-2. Quit nios-run and start your terminal application (e.g. start
-Hyperterminal or minicom).
-
-3. Download the u-boot code to RAM. When using Hyperterminal, do the
-following:
-
-   a.  From the u-boot command prompt start a binary download to SRAM:
-
-    ==> loadb 800000
-
-    b. Download u-boot.bin using kermit.
-
-4. From the U-Boot command prompt, erase flash 0x40000 to 0x5ffff:
-
-    ==> erase 1:4-5
-
-5. Copy the binary image from SRAM to flash:
-
-    ==> cp.b 800000 40000 10000
-
-U-Boot will now automatically start when the board is powered on or
-reset using the Standard-32 configuration. To start U-Boot with the
-Safe-32 configuration, enter the following GERMS command:
-
-    + g 40000
-
-5. Active Serial Memory Interface (ASMI) Support
-================================================
-ASMI is fully supported in U-Boot. Please note that ASMI is supported
-only on Cyclone devices. Do not expect ASMI to work with Stratix or
-APEX devices.
-
-		 ************* IMPORTANT *************
-	 ===================================================
-	IN ORDER FOR THE NIOS ASMI TO OPERATE PROPERLY, THE
-	CYCLONE DEVICE MUST BE CONFIGURED USING JTAG OR ASMI.
-
-There are two techniques you can use to bootstrap the ASMI. The
-first is to use the program_epcs utility that is part of Altera's SDK.
-But I've found program_epcs to be slow and cumbersome at best.
-
-An undocumented alternative is to use the Quartus device programing
-interface:
-
-    1. Select "Active Serial" mode.
-
-    2. Choose the xxx.pof file. For example, for the standard_32
-       configuration use the "standard_32.pof" file.
-
-    3. Attach your ByteBlaster to J28. Make sure you have the
-       cable attached properly -- the orientation of J28 is
-       different than J24 (the JTAG header). On J28, pin 1 is on
-       the bottom row, left-most pin.
-
-    4. Press and hold the "Power-On Reset" switch (SW10). You will
-       see the green "Loading" and red "Error" LEDs (LED3 and LED4)
-       in the on state.
-
-    5. While holding down the "Power-On Reset" switch, start the
-       programming sequence. This only takes about 10 seconds.
-
-    6. After programming is complete, release the "Power-On Reset"
-       switch. The Cyclone device should now load its configuration
-       from the EPCS4 (U59). The green "User" LED (LED 1) should be
-       blinking if the device was successfully loaded via ASMI.
-
-    7. Remove the ByteBlaster cable. The cable must be removed to
-       allow the Nios ASMI access to the EPCS4 device.
-
-After you have successfully programmed a configuration into the
-EPCS4, the ASMI will be used to load the Cyclone configuration
-unless the "Force Safe" switch (SW9) is pressed.
-
-NOTE: To maximize the amount of space available for program use,
-you can enable configuration compression in Quartus. With compression
-enabled, the size of the standard_32 configuration data is
-approximately 192 KBytes.
-
-To use the U-Boot ASMI commands, try typing "help asmi" at the
-command prompt. The command "asmi info" will show the current
-status of the ASMI.

-====================================================================
-
-This file contains information regarding U-Boot and the Altera
-Nios Development Kit, Startix Edition (DK-1S10). For general Nios
-information see doc/README.nios.
-
-Most stuff of this file was borrowed and based on README.dk1c20,
-the DK-1C20 related information file.
-
-For those interested in contributing ... see HELP WANTED section
-in doc/README.nios.

-	3. CPU Variations
-	4. Examples
-	5. Programming U-Boot into FLASH with GERMS
-
-====================================================================
-
-1. Files
-=========
-	board/altera/dk1s10/*
-	include/configs/DK1S10.h
-
-2. Memory Organization
-=======================
-
-	-The heap is placed below the monitor (U-Boot code).
-	-Global data is placed below the heap.
-	-The stack is placed below global data (&grows down).
-
-3. CPU Variations
-=================
-
-There are more than one NIOS CPU variation for the DK-1S10. U-Boot
-supports the following CPU configurations:
-
-	- Altera Standard 32 (make DK1S10_standard_32_config)
-	- Microtronix LDK 2.0 (make DK1S10_mtx_ldk_20_config)
-
-4. Examples
-============
-
-The hello_world example was never tested on DK-1S10. Neverthelse
-it should work as far as possible, because the DK-1S10 port is
-more than ninetieth percents equal to the DK-1C20 port and at
-this platform the hello_world example was already tested
-successfully (see README.dk1c20).
-
-
-5. Programming U-Boot into FLASH with GERMS
-============================================
-The current version of the DK-1S10 port with the default
-configuration settings occupies about 78 KBytes of flash.
-A minimal configuration occupies less than 60 KByte
-(network support disabled).
-
-To program U-Boot into the DK-1S10 flash using GERMS do the
-following:
-
-1. From the command line, download U-Boot using the nios-run:
-
-	$ nios-run -r u-boot.srec
-
-This takes about 45 seconds (GERMS is not very speedy here).
-After u-boot is downloaded it will be executed. You should
-see the following:
-
-    U-Boot 1.0.2 (Jan 28 2004 - 19:02:30)
-
-    CPU: Nios-32 Rev. 3.3 (0x3038)
-    Reg file size: 256 LO_LIMIT/HI_LIMIT: 2/14
-    Board: Altera Nios 1S10 Development Kit
-    In:    serial
-    Out:   serial
-    Err:   serial
-    DK1S10 >
-
-
-2. Quit nios-run and start your terminal application (e.g. start
-   Hyperterminal or minicom).
-
-3. Download the u-boot code to RAM. When using Hyperterminal, do the
-   following:
-
-   a. From the u-boot command prompt start a binary download to
-      SRAM / SDRAM:
-
-      at the Altera Standard 32 to SRAM:
-
-	==> loadb 800000
-
-      at the Microtronix LDK 2.0 to SDRAM:
-
-	==> loadb 1010000
-
-   b. Download u-boot.bin using kermit.
-
-4. From the U-Boot command prompt, erase flash:
-
-   at the Altera Standard 32 from 0x40000 to 0x5ffff:
-
-	==> erase 1:4-5
-
-   at the Microtronix LDK 2.0 from 0x8000000 to 0x81ffff:
-
-	==> erase 1:0-1
-
-5. Copy the binary image from SRAM / SDRAM to flash:
-
-   at the Altera Standard 32 to SRAM:
-
-	==> cp.b 800000 40000 ${filesize}
-
-   at the Microtronix LDK 2.0 to SDRAM:
-
-	==> cp.b 1010000 8000000 ${filesize}
-
-U-Boot will now automatically start when the board is powered on or
-reset using the Standard-32 configuration. To start U-Boot with the
-Safe-32 configuration, enter the following GERMS command:
-
-    + g 40000

-1. OVERVIEW
-------------
-
-U-Boot has been successfully tested on the Nios Cyclone development
-board using both the 'safe' and 'standard 32' configurations with
-Nios CPU revision 3.1 (CPU_ID = 0x3018). U-Boot can be used with
-or without the GERMS monitor. The initial version of U-Boot for the
-Cyclone development kit is about 60 Kbyte and will fit in a single
-sector of on-board FLASH. Only the Nios 32-bit CPU is supported.
-
-1.1 GERMS Monitor
-------------------
-If GERMS is just not enough, then U-Boot is a great antibiotic.
-You will be very pleased with its high degree of configurability
-and its rich feature set.
-
-A few of the most obvious limitations of GERMS are overcome by
-using U-Boot (See 'Brain Damage'). Most notably, you can use
-minicom or Hyperterminal (duh).
-
-1.2 Altera Source Code
------------------------
-The Nios port does NOT include ANY sources that Altera has the
-copyright. This was a conscious decision ... not an accident.
-The Altera license is not clear in terms of distributing Altera
-sources (when altera silicon is not involved). This isn't really
-a problem as little, if any, of the Altera source contains
-features that are not already available in U-Boot.
-
-1.3 Debugging via OCI
----------------------
-The Nios port supports debugging with gdb and/or nios-console
-via the JTAG port. Stubs for debugging with gdb via the serial
-port are not currently implemented.
-
-
-2. CONFIGURATION OPTIONS/SETTINGS
-----------------------------------
-
-2.1 Nios-specific Options/Settings
------------------------------------
-All configuration options/settings that are specific to Nios begin
-with "CONFIG_NIOS_", "CONFIG_SYS_NIOS_", or "CONFIG_SYS_NIOS_CPU_".
-
-The configuration follows a two-stage process. In the first stage
-the NIOS CPU core will defined like defined in Alteras SOPC Builder.
-At this point we use the "CONFIG_SYS_NIOS_CPU_" defines exclusively. For
-more informations about all the definitions you have to setup see
-into current board configurations and doc/README.nios_CFG_NIOS_CPU.
-
-In second stage we bring the NIOS CPU configuration in relation to
-U-Boot configuration options/settings. The following is a list of
-currently defined Nios-specific options/parameters used inside of
-U-Boot. If any options are related to Standard-32 Nios SDK
-excalibur.h definitions, the related definition follows the
-description).
-
-CONFIG_NIOS -- defined for all Nios-32 boards.
-
-CONFIG_SYS_NIOS_CONSOLE -- the base address of the console UART or the JTAG
-	stdio port. To enable a console via JTAG, define
-	CONFIG_CONSOLE_JTAG and set CGF_NIOS_CONSOLE to the base address
-	of the JTAG stdio port (normally OCI base + 0x00fa). Then
-	run nios-console with the -w option.
-	(standard-32: nasys_uart_0 resp. na_uart1_base).
-
-CONFIG_SYS_NIOS_FIXEDBAUD -- defined if the console UART PTF fixed_baud
-	parameter is set to '1'.
-
-CONFIG_SYS_NIOS_MULT_HW -- use full hardware multiply (not yet implemented).
-
-CONFIG_SYS_NIOS_MULT_MSTEP -- use hardware assisted multiply using the
-	MSTEP instruction (not yet implemented).
-
-CONFIG_SYS_NIOS_TMRBASE -- the base address of the timer used to support
-	xxx_timer routines (e.g. set_timer(), get_timer(), etc.).
-	(standard-32: nasys_timer_1 resp. na_lo_priority_timer2_base).
-
-CONFIG_SYS_NIOS_TMRIRQ -- the interrupt request (vector number) assigned to
-	the timer. (standard-32: nasys_timer_1_irq resp.
-	na_low_priority_timer2_irq).
-
-CONFIG_SYS_NIOS_TMRMS -- the period of the timer in milliseconds.
-
-CONFIG_SYS_NIOS_TMRCNT -- the preloadable counter value for the timer if it has
-	no fixed period.
-
-CONFIG_SYS_NIOS_ASMIBASE -- the base address of the ASMI peripheral.
-	(standard-32: na_asmi_base).
-
-CONFIG_SYS_NIOS_SPIBASE -- the base address of the SPI master (!) peripheral.
-	(nasys_spi_0)
-
-CONFIG_SYS_NIOS_SPIBITS -- the amount of configured SPI data bits in PTF.
-	This value can be 8 or 16 only! (PTF: databits)
-
-
-2.2 Differences in U-Boot Options/Settings
--------------------------------------------
-Some 'standard' U-Boot options/settings are treated differently in
-the Nios port. These are described below.
-
-CONFIG_SYS_GBL_DATA_OFFSET -- in the Nios port, this is the offset of the
-	global data structure in the Nios memory space. More simply,
-	the address of global data.
-
-
-3. ASSEMBLY CODING
--------------------
-
-In browsing the assembly source files, you may notice the absence
-of the 'magic macros' (e.g. MOVIA, MOVIP, ADDIP etc.). This is
-deliberate. The documentation for the magic macros is scant and
-it is hard to find ... it does not appear in the Nios programmer's
-manual, nor does it appear in the assembler manual. Regardless,
-the macros actually do very little to improve readability anyway.
-
-With this in mind, all assembler modules use only instructions that
-appear in the Nios programmer's manual OR are directly supported
-by the nios-elf toolchain. For example, the 'dec %rB' instruction
-is an alias for 'subi %rB,1' that is supported by the assembler
-but does not appear in the programmer's manual.
-
-
-4. BOOT PROCESS
----------------
-
-4.1 Boot process over GERMS
----------------------------
-When the NIOS CPU catch a reset signal it will begin to be running
-code from CONFIG_SYS_NIOS_CPU_RST_VECT. Normally at this place it will
-find the GERMS monitor. That's the case for the generic NIOS CPU
-configuration "standard_32". When the GERMS monitor starts running,
-it performs important system initializations and then looks for
-executable code in flash, using the following steps:
-
-    1. Examining the two bytes at CONFIG_SYS_NIOS_CPU_FLASH_BASE + 0x04000C.
-    2. Examining the button 0 on the PIO CONFIG_SYS_NIOS_CPU_BUTTON_PIO.
-    3. If the button is not pressed and the two bytes contain 'N'
-       and 'i', the monitor executes a CALL to location
-       CONFIG_SYS_NIOS_CPU_FLASH_BASE + 0x040000.
-    4. If the code is not executed in step 3 or the code returns,
-       then prints an 8-digit version number to STDOUT and waits for
-       user commands from STDIN.
-
-In normal case, for "standard_32", STDIN and STDOUT are the first
-serial port.
-
-4.2 Return to GERMS command line
---------------------------------
-During the boot process, the GERMS monitor checks for the existence
-of application software in flash memory. If found, the processor
-immediately executes the code. To return program execution to the
-GERMS monitor (that is, avoid running code stored in flash memory):
-
-    1. Hold down CONFIG_SYS_NIOS_CPU_BUTTON_PIO, button number 0.
-    2. Press then release the CPU reset button.
-    3. Release CONFIG_SYS_NIOS_CPU_BUTTON_PIO, button number 0.
-
-
-5. DEBUGGING WITH GDB
----------------------
-
-Debug sessions using gdb are currently supported only via JTAG. The
-stubs for debugging via a serial port are not implemented. To enable
-the gdb JTAG stubs, simply reference _brkpt_hw_int and _brkpt_sw_int
-at vector table offsets 3 and 4, respectively. For an example, see
-board/altera/dk1c20/vectors.S.
-
-5.1 Vector Table Initialization and ROM Stubs
----------------------------------------------
-If CONFIG_ROM_STUBS is defined, the debug breakpoint and single step
-entries in the vector table are restored to their initial values
-immediately _after_ initializing the vector table. Defining this macro
-is useful when ROM-based stubs are implemented.
-
-NOTE: The default GERMS monitor does NOT implement gdb stubs, nor does
-it initialize the vector table. Therefore, when debugging U-Boot, you
-should NOT set a software breakpoint prior to vector table initialization.
-
-5.2 Starting a Debug Session
-----------------------------
-If you're not familiar with gdb, you follow these step-by-step instructions.
-These instructions are NOT the only way to start a debug session, but they
-cover most of the individual functions to get you started.
-
-	1.  Start the JTAG gdb server. Open a Nios shell window and start
-	the server. When the server is started you must provide the base
-	address of the OCI core. For example, when using the Cyclone
-	development kit (DK1C20):
-
-		$ nios-gdb-server --ocibase=0x00920800 --tcpport=2342
-
-	2.  Start gdb. Open a Nios shell window, change to the top-level
-	U-Boot directory and start gdb, specifying the u-boot elf file:
-
-		$ nios-elf-gdb u-boot
-
-	3.  Update target settings. From the file menu, select
-	"Target Settings ..." and select the following, then click 'Ok':
-
-		Target:	Remote/TCP
-		Port :	2342   (same as in step 1)
-		Display download dialog: checked
-		All other check boxes: unchecked
-
-	4.  Connect to the target. Select menu: 'Run->Connect to target'.
-	You should see a dialog box indicating the you successfully connected
-	to the target.
-
-	5.  Download U-Boot. Select menu: 'Run->Download'.
-
-	6.  Open a gdb console window and set the source directory paths.
-	Select menu: 'View->Console'. In the console window, enter the
-	following commands, then close the console window:
-
-		(gdb) directory common
-		(gdb) directory arch/nios/cpu
-		(gdb) directory arch/nios/lib
-		(gdb) directory board/altera/dk1c20
-
-	Note that the last command is for the DK1C20 board only. If you
-	are using another board, specify that board's directory.
-
-	7.  Open the file board.c (using the file menu in the lower
-	left hand corner). Scroll to the board_init() routine and set
-	a breakpoint.
-
-	8. Run U-Boot. Just click on the run icon, or select menu:
-	'Run->Run'. U-Boot should start running, then break at your
-	breakpoint.
-
-	9.  Have fun & start learning more about gdb.
-
-
-5.3 For advanced Users
-----------------------
-A few notes for those more familiar with gdb.
-
-	-Serial port stubs are not implemented. Sorry, but it's just not
-	worth _my_ effort. The JTAG stubs work great and are ridiculously
-	simple to implement.
-
-	-If you need to debug the early startup code (prior to the vector
-	table initialization), use the nios-console debugger.
-
-	- Connect, download & run -- there are some problems here. Connect
-	download and run seperately to avoid trouble.
-
-6. BRAIN DAMAGE
-----------------
-
-This section describes some of the unfortunate and avoidable aspects
-of working with the Nios CPU ... and some things you can do to
-reduce your pain.
-
-6.1 GERMS doesn't work with Hyperterminal
-------------------------------------------
-GERMS doesn't do CR/LF mapping that is compatible with Hyperterminal
-(or minicom) -- geez. Regardless of you opion of Hyperterminal, this
-sad design decision is remedied by using U-Boot.
-
-6.2 cygwin Incompatibility
----------------------------
-The version of cygwin distributed with the nios GNUPro toolchain is
-out-of-date and incompatible with the latest cygwin distributions.
-In addition, many of the standard utilities are very dated as well.
-If you try to download and build the lastest version of grep for
-example, you'll quickly realize that a native gcc is not available
-(the next topic) which leads to U-Boot build problems (following
-topic).
-
-The solution ... well, you can wait for Altera ... or build as
-set of tools for linux.
-
-6.3 No native gcc
-------------------
-I'm not sure how this one slipped through the cracks ... but it is
-a real pain. Basically, if you want to build anything for the native
-environment -- forget it! A native (cygwin) gcc is not distributed,
-and the old version of cygwin makes locating one challenging.
-
-The solution ... same as above. Just download the gcc source from
-Altera and build up a set of cross tools for your favorite linux
-distro. Anybody who wants to use an already precompiled NIOS cross
-toolchain can it found in the CDK4NIOS project hosted by Source
-Forge at http://cdk4nios.sourceforge.net.
-
-6.4 Can't build default U-Boot
--------------------------------
-By default, when you build U-Boot you will be building some native
-tools along with the target elf, bin, and srec files. Without a
-native gcc, this (obviously) causes problems.
-
-For developers using the Altera cygwin tools you can remove the
-'tools' directory from SUBDIRS in the top-level Makefile. You will
-also have to edit common/Makefile:
-
-Replace:
-env_embedded.o: env_embedded.c ../tools/envcrc
-	$(CC) $(AFLAGS) -Wa,--no-warn \
-		-DENV_CRC=$(shell ../tools/envcrc) \
-		-c -o $@ env_embedded.c
-
-With:
-env_embedded.o: env_embedded.c
-	$(CC) $(AFLAGS) -Wa,--no-warn \
-		-DENV_CRC=0 \
-		-c -o $@ env_embedded.c
-
-BTW, thats a 'zero' ... not the letter 'O'. And not that the
-"../tools/envcrc" dependency is removed.
-
-
-7. HELP WANTED
----------------
-
-There are plenty of areas where help is needed. Here's are some ideas
-for those interested in contributing:
-
--CompactFlash. Port & test CF/FAT.
-
--Bedbug. Develop bedbug for Nios ... or at least provide a disassemble
- command.
-
--Add boot support for ucLinux (niosnommu).
-
--Implement (don't copy Altera code) the __mulxx routines using the
- MSTEP and MUL instructions (e.g. CONFIG_SYS_NIOS_MULT_HW and CONFIG_SYS_NIOS_MULT_MSTEP).
-
