* ppc4xx: Fix Arches DDR2 initializationStefan Roese2009-07-28-12/+18
| | | | | | | | | Testing on AMCC Arches with the latest U-Boot version yielded that DDR2 initialization is currently broken. U-Boot hangs upon relocation to SDRAM or crashes with random traps. This patch fixes this problem. Arches now uses a different WRDTR and CLKTR default setting than Canyonlands/Glacier. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add chip_config command to AMCC Kilauea eval boardStefan Roese2009-07-24-298/+76
| | | | | | | | This patch removes the "alterpll" command and replaces it with the now ppc4xx standard "chip_config" command to configure the I2C bootstrap EEPROM. Signed-off-by: Stefan Roese <sr@denx.de>
* Add "chip_config" command for PPC4xx bootstrap configurationStefan Roese2009-07-24-197/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a generic command for programming I2C bootstrap eeproms on PPC4xx. An implementation for Canyonlands board is included. The command name is intentionally chosen not to be PPC4xx specific. This way other CPU's/SoC's can implement a similar command under the same name, perhaps with a different syntax. Usage on Canyonlands: => chip_config Available configurations (I2C address 0x52): 600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100 600-nand - NAND CPU: 600 PLB: 200 OPB: 100 EBC: 100 800-nor - NOR CPU: 800 PLB: 200 OPB: 100 EBC: 100 800-nand - NAND CPU: 800 PLB: 200 OPB: 100 EBC: 100 1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100 1000-nand - NAND CPU:1000 PLB: 200 OPB: 100 EBC: 100 1066-nor - NOR CPU:1066 PLB: 266 OPB: 88 EBC: 88 *** 1066-nand - NAND CPU:1066 PLB: 266 OPB: 88 EBC: 88 => chip_config 600-nor Using configuration: 600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100 done (dump via 'i2c md 52 0.1 10') Reset the board for the changes to take effect Other 4xx boards will be migrated to use this command soon as well.

* ppc4xx: Fix FDT EBC mappings on CanyonlandsFelix Radensky2009-07-08-2/+4
| | | | | | | | | | This patch fixes 2 problems with FDT EBC mappings on Canyonlands. First, NAND EBC mapping was missing, making Linux NAND driver unusable on this board. Second, NOR remapping code assumed that NOR is always on CS0, however when booting from NAND NOR is on CS3.

* General help message cleanupWolfgang Denk2009-06-12-40/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc4xx: Add Sequoia RAM-booting targetStefan Roese2009-06-12-3/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds another build target for the AMCC Sequoia PPC440EPx eval board. This RAM-booting version is targeted for boards without NOR FLASH (NAND booting) which need a possibility to initially program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000) configured to setup the SDRAM, this debugger can load this RAM- booting image to the target address in SDRAM (in this case 0x1000000) and start it there. Then U-Boot's standard NAND commands can be used to program the NAND FLASH (e.g. "nand write ..."). Here the commands to load and start this image from the BDI2000: 440EPX>reset halt 440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin 440EPX>go 0x1000000 Please note that this image automatically scans for an already initialized SDRAM TLB (detected by EPN=0). This TLB will not be cleared. This TLB doesn't need to be TLB #0, this RAM-booting version will detect it and preserve it. So booting via BDI2000 will work and booting with a complete different TLB init via U-Boot works as well. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Fixup chip-selects in dtb for NAND-booting SequoiaStefan Roese2009-04-16-2/+56
| | | | | | | | | | | | | | | | | | | | Currently the NOR & NAND support in Linux only works for the "standard" Sequoia, the version booting for NOR flash. The NAND-booting version has the chip-selects swapped. Here the chip-select mappings: "Standard" NOR-booting version: CS0 NOR CS3 NAND NAND-booting version: CS0 NAND CS3 NOR With this path the dtb gets fixed-up, so that the correct chip-select numbers are patched in the dtb enabling correct NOR & NAND support in Linux on the NAND-booting Sequoia version.

* ppc4xx: Sequoia: Fix TLB reassignment in NAND booting codeStefan Roese2009-03-26-1/+1
| | | | | | | | | | This patch fixes a bug in the Sequoia TLB init code to reconfigure the correct TLB (boot space) after running from RAM. This bug was introduced with patch 4d332dbeb08f5863d1ea69d91a00c5499d3a87ed [ppc4xx: Make Sequoia boot vxWorks] which changed the order of the TLB in the Sequoia init.S file.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-66/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the 440GX interrupt handling so that the common 4xx code can be used. The 440GX is an exception to all other 4xx variants by having the cascading interrupt vectors not on UIC0 but on a special UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt handling is simpler without any 440GX special cases. Also some additional cleanup to cpu/ppc4xx/interrupt.c is done. Signed-off-by: Stefan Roese <sr@denx.de>

This way only the vectors need to get defined for new PPC's. Also only the really used interrupt vectors are now defined. This makes definitions for new PPC versions easier and less error prone. Another part of this patch is that the 4xx emac driver got a little cleanup, since now the usage of the interrupts is clearer. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Canyonlands: Disable the RTC M41T62 square wave outputStefan Roese2008-06-12-0/+11
| | | | | | | | | | | | | | | | | This patch disables the square wave output of the M41T62 RTC used on Canyonlands & Glacier. Here the explanation: The serial real-time clock part used in the design is an STMicro M41T62. This part has a full-time 32KHz square wave output that is connected to the TmrClk input to the processor. The default state for this square wave output is enabled so the output runs continuously when the board is powered normally and also from the battery. The TmrClk input to the processor goes to ground when the power is removed from the board/processor, and therefore the running square wave output is driving ground which drains the battery quickly.

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-11/+11
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code.
