+You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html

+Overview
+--------
+The MPC8544DS system is similar to the 85xx CDS systems such
+as the MPC8548CDS due to the similar E500 core. However, it
+is placed on the same board as the 8641 HPCN system.
+
+
+Flash Banks
+-----------
+Like the 85xx CDS systems, the 8544 DS board has two flash banks.
+They are both present on boot, but there locations can be swapped
+using the dip-switch SW10, bit 2.
+
+However, unlike the CDS systems, but similar to the 8641 HPCN
+board, a runtime reset through the FPGA can also affect a swap
+on the flash bank mappings for the next reset cycle.
+
+Irrespective of the switch SW10[2], booting is always from the
+boot bank at 0xfff8_0000.
+
+
+Memory Map
+----------
+
+0xff80_0000 - 0xffbf_ffff Alernate bank 4MB
+0xffc0_0000 - 0xffff_ffff Boot bank 4MB
+
+0xffb8_0000 Alternate image start 512KB
+0xfff8_0000 Boot image start 512KB
+
+
+Flashing Images
+---------------
+
+For example, to place a new image in the alternate flash bank
+and then reset with that new image temporarily, use this:
+
+ tftp 1000000 u-boot.bin.8544ds
+ erase ffb80000 ffbfffff
+ cp.b 1000000 ffb80000 80000
+ pixis_reset altbank
+
+
+To overwrite the image in the boot flash bank:
+
+ tftp 1000000 u-boot.bin.8544ds
+ protect off all
+ erase fff80000 ffffffff
+ cp.b 1000000 fff80000 80000
+
+Other example U-Boot image and flash manipulations examples
+can be found in the README.mpc85xxcds file as well.
+
+
+The pixis_reset command
+-----------------------
+A new command, "pixis_reset", is introduced to reset mpc8641hpcn board
+using the FPGA sequencer. When the board restarts, it has the option
+of using either the current or alternate flash bank as the boot
+image, with or without the watchdog timer enabled, and finally with
+or without frequency changes.
+
+Usage is;
+
+ pixis_reset
+ pixis_reset altbank
+ pixis_reset altbank wd
+ pixis_reset altbank cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
+ pixis_reset cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
+
+Examples;
+
+ /* reset to current bank, like "reset" command */
+ pixis_reset
+
+ /* reset board but use the to alternate flash bank */
+ pixis_reset altbank
+
+ /* reset board, use alternate flash bank with watchdog timer enabled*/
+ pixis_reset altbank wd
+
+ /* reset board to alternate bank with frequency changed.
+ * 40 is SYSCLK, 2.5 is COREPLL ratio, 10 is MPXPLL ratio
+ */
+ pixis-reset altbank cf 40 2.5 10
+
+Valid clock choices are in the 8641 Reference Manuals.
+
+
+Using the Device Tree Source File
+---------------------------------
+To create the DTB (Device Tree Binary) image file,
+use a command similar to this:
+
+ dtc -b 0 -f -I dts -O dtb mpc8544ds.dts > mpc8544ds.dtb
+
+Likely, that .dts file will come from here;
+
+ linux-2.6/arch/powerpc/boot/dts/mpc8544ds.dts
+
+After placing the DTB file in your TFTP disk area,
+you can download that dtb file using a command like:
+
+ tftp 900000 mpc8544ds.dtb
+
+Burn it to flash if you want.
+
+
+Booting Linux
+-------------
+
+Place a linux uImage in the TFTP disk area too.
+
+ tftp 1000000 uImage.8544
+ tftp 900000 mpc8544ds.dtb
+ bootm 1000000 - 900000
+
+Watch your ethact, netdev and bootargs U-Boot environment variables.
+You may want to do something like this too:
+
+ setenv ethact eTSEC3
+ setenv netdev eth1

+1. Building U-Boot
+------------------
+The SBC8641D code is known to build using ELDK 4.1.

+ Configuring for sbc8641d board...
+
+ $ make

+
+2. Switch and Jumper Settings
+-----------------------------
+All Jumpers & Switches are in their default positions. Please refer to
+the board documentation for details. Some settings control CPU voltages
+and settings may change with board revisions.
+
+3. Known limitations
+--------------------
+PCI:
+ The PCI command may hang if no boards are present in either slot.

+
+Storage of the board specific values (ethaddr...)
+-------------------------------------------------
+
+The board specific environment variables that should be unique
+for each individual board, can be stored in the I2C EEPROM. This
+will be done from offset 0x80 with the length of 0x80 bytes. The
+following command can be used to store the values here:
+
+=> setdef de:20:6a:ed:e2:72 de:20:6a:ed:e2:73 AB0001
+
+ ethaddr eth1addr serial#
+
+Now those 3 values are stored into the I2C EEPROM. A CRC is added
+to make sure that the values get not corrupted.
+
+
+SW-Reset Pushbutton handling:
+-----------------------------
+
+The SW-reset push button is connected to a GPIO input too. This
+way U-Boot can "see" how long the SW-reset was pressed, and a
+specific action can be taken. Two different actions are supported:
+
+a) Release after more than 5 seconds and less then 10 seconds:
+ -> Run POST
+
+ Please note, that the POST test will take a while (approx. 1 min
+ on the 128MByte board). This is mainly due to the system memory
+ test.
+
+b) Release after more than 10 seconds:
+ -> Restore factory default settings
+
+ The factory default values are restored. The default environment
+ variables are restored (ipaddr, serverip...) and the board
+ specific values (ethaddr, eth1addr and serial#) are restored
+ to the environment from the I2C EEPROM. Also a bootline parameter
+ is added to the Linux bootline to signal the Linux kernel upon
+ the next startup, that the factory defaults should be restored.
+
+The command to check this sw-reset status and act accordingly is
+
+=> chkreset
+
+This command is added to the default "bootcmd", so that it is called
+automatically upon startup.
+
+Also, the 2 LED's are used to indicate the current status of this
+command (time passed since pushing the button). When the POST test
+will be run, the green LED will be switched off, and when the
+factory restore will be initiated, the reg LED will be switched off.
+
+
+Loggin of POST results:
+-----------------------
+
+The results of the POST tests are logged in a logbuffer located at the end
+of the onboard memory. It can be accessed with the U-Boot command "log":
+
+=> log show
+<4>POST memory PASSED
+<4>POST cache PASSED
+<4>POST cpu PASSED
+<4>POST uart PASSED
+<4>POST ethernet PASSED
+
+The DENX Linux kernel tree has support for this log buffer included. Exactly
+this buffer is used for logging of all kernel messages too. By enabling the
+compile time option "CONFIG_LOGBUFFER" this support is enabled. This way you
+can access the U-Boot log messages from Linux too.
