* | Move arch/ppc to arch/powerpcStefan Roese2010-04-21-11/+11
|/ | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

| | | | | | | | | | The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* ppc4xx: Kilauea: Add CPLD version detection and EBC reconfigurationStefan Roese2010-01-23-1/+39
| | | | | | | | | | | | | | | A newer CPLD version on the 405EX evaluation board requires a different EBC controller setup for the CPLD register access. This patch adds a CPLD version detection for Kilauea and code to reconfigure the EBC controller (chip select 2) for the old CPLD if no new version is found. Additionally the CPLD version is printed upon bootup: Board: Kilauea - AMCC PPC405EX Evaluation Board (CPLD rev. 0) Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Wolfgang Denk <wd@denx.de> Cc: Zhang Bao Quan <bqzhang@udtech.com.cn>

* POST: Remove duplicated post_hotkey_pressed() functionsStefan Roese2009-12-07-78/+0
| | | | | | | | | | | | | This patch introduces a weak default function for post_hotkey_pressed(), returning 0, for boards without hotkey support. The long-running tests won't be started on those boards. This default function was implemented in many board directories. By implementing this weak default we can remove all those duplicate versions. Boards with hotkey support, can override this weak default function by defining one in their board specific code. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Sequoia: Add chip_config commandStefan Roese2009-10-23-232/+125
| | | | | | | | | | | | | | | This patch removes the Sequoia "bootstrap" command and replaces it with the now common command "chip_config". Please note that the patches with the dynamic PCI sync clock configuration have to be applied, before this one should go in. This is because Sequoia has 2 different bootstrap EEPROMs, and the old bootstrap command configured different values depending on the detected PCI async clock (33 vs. 66MHz). With the PCI sync clock patches, this is not necessary anymore. The PCI sync clock will be configured correctly on-the-fly now. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Fix "chip_config" command for AMCC ArchesStefan Roese2009-08-18-16/+18
| | | | | | | | | | This patch fixes the "chip_config" command for I2C bootstrap EEPROM configuration. First it changes the I2C bootstrap EEPROM address to 0x54 as this is used on Arches (instead of 0x52 on Canyonlands/ Glacier). Additionally, the NAND bootstrap settings are removed for Arches since Arches doesn't support NAND-booting. 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.

* 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>
