2013-03-01armv7/snow: Add S5P MSHC initialization in ROM stage.Hung-Te Lin
The SD/MMC interface on Exynos 5250 must be first configured with, GPIO, and pinmux settings before it can be detected and used in ramstage / payload. Verified on armv7/snow and successfully boot into ramstage.

2013-02-28Revert "ARMv7: drop special handling for stages.c"Ronald G. Minnich
This breaks booting, and in fact stages.c is always going to be special: for it to work it has to be compiled for arm only, no thumb allowed. It's probably better to leave the stages.o target in explicitly so it's clear that it has to be compiled with a particular set of flags, rather than try to remember that we must always have the default rules no break stages.c compilation. That would be a mess. I will be pushing a CL to get rid of the assembly dump, but will be a trivial fix.

2013-02-25AMD Fam14 boards: Set P_BLK length to 6 for all processorsPaul Menzel
Currently on for example on AMD Persimmon and ASRock E350M1 Linux complains, that the PBLK length is invalid [1]. ACPI: Invalid PBLK length [0] Consequently, frequency scaling might not work correctly, though for these two boards it seems to work according to PowerTOP. Indeed, according to the ACPI specification [2], setting PBlockLength to 0 is only allowed if there is no PBlockAddress. Otherwise it has to be set to 6. 18.5.93 Processor (Declare Processor) […] PBlockAddress provides the system I/O address for the processors register block. Each processor can supply a different such address. PBlockLength is the length of the processor register block, in bytes and is either 0 (for no P_BLK) or 6. With one exception, all processors are required to have the same PBlockLength. The exception is that the boot processor can have a non-zero PBlockLength when all other processors have a zero PBlockLength. It is valid for every processor to have a PBlockLength of 0. And that is exactly what Linux is checking in `drivers/acpi/processor_driver.c` [3]. static int acpi_processor_get_info(struct acpi_device *device) { […] /* * On some boxes several processors use the same processor bus id. * But they are located in different scope. For example: * \_SB.SCK0.CPU0 * \_SB.SCK1.CPU0 * Rename the processor device bus id. And the new bus id will be * generated as the following format: * CPU+CPU ID. */ sprintf(acpi_device_bid(device), "CPU%X", pr->id); ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Processor [%d:%d]\n", pr->id, pr->acpi_id)); if (!object.processor.pblk_address) ACPI_DEBUG_PRINT((ACPI_DB_INFO, "No PBLK (NULL address)\n")); else if (object.processor.pblk_length != 6) printk(KERN_ERR PREFIX "Invalid PBLK length [%d]\n", object.processor.pblk_length); else { pr->throttling.address = object.processor.pblk_address; pr->throttling.duty_offset = acpi_gbl_FADT.duty_offset; pr->throttling.duty_width = acpi_gbl_FADT.duty_width; pr->pblk = object.processor.pblk_address; /* * We don't care about error returns - we just try to mark * these reserved so that nobody else is confused into thinking * that this region might be unused.. * * (In particular, allocating the IO range for Cardbus) */ request_region(pr->throttling.address, 6, "ACPI CPU throttle"); } […] } This issue has proliferated to all AMD based boards so fix it for all of them by setting P_BLK length to 6. The DSDT of for example AMD Parmer and AMD Thatcher also set it to 6 everywhere so this solution is taken instead of setting the P_BLK system I/O base to 0 for all but the first processor which is how it is done for earlier AMD based boards. As note having to set this manually should not be needed and this should be autogenerated as done for most of the Intel boards and the AMD K8 based boards (`src/cpu/amd/model_fxx/powernow_acpi.c`).

2013-02-25AMD boards: ACPI DSDT: Use COREBOOT for the OEM Table ID fieldPaul Menzel
The DSDT header contains the fields OEMID and OEM Table ID. See for example ACPI specification 4.0a [1] 5.2.11.1 Differentiated System Description Table (DSDT) on page 135. There Table 5-16 contains the descriptions. Field Byte Length Byte Offset Description =================================================== OEMID 6 10 OEM ID OEM Table ID 8 16 The manufacture model ID. Currently in coreboot there is no common method what to put in these fields. Mostly Intel based boards populate it with "CORE " ore "COREv4" and AMD based boards populate it with the board vendor and model number, abbreviated appropriately to fit into these fields. On most boards the proprietary vendor BIOS seems to leave these fields – displayed with `sudo dmidecode` under System Information – blank To Be Filled By O.E.M. and fill out the Base Board Information with the board vendor and model name. In [2] Jens Rottmann argues that the this is really just the table ID used for naming it and that »99% of the DSDT code is not board specific«. Both approaches seem to have their advantages, but using the second one, developers often seem to forget to update them (for example AMD Thather). The current situation is at least not optimal. and therefore at least unify the string in the OEM Table ID. If unifying the OEM ID is also a good idea this should be done too. If later on it should be decided that the board vendor and model should be used again, this should be somehow derived from Kconfig. The following command was used for the change [3]. $ git grep -l '\/\* TABLE ID \*\/' | xargs sed -i '/TABLE ID/s/"\([^"]*\)"/"COREBOOT"/' This patch is split out from [2].

To reduce the differences between these file name the enabling device function in the directory `src/mainboard` uniformly `mainboard_enable` [1]. Thanks to the awesome help of gnomon and BlastHardcheese in the IRC channel #sed on <irc.freenode.net>. gnomon came up with the following command to do the actual work. $ cd src/mainboard $ for f in */*/mainboard.c ; \ > do src="$(awk '/\.enable_dev = /{v=$NF; sub(/,$/,"",v); print v}' "$f")" ; \ > [[ -z $src ]] && continue ; \ > printf '%s\n' "g/${src}/s/${src}\([,(]\)/mainboard_enable\1/p" w | ed -s "$f" ; \ > done `src/mainboard/digitallogic/msm586seg/mainboard.c` and `src/mainboard/technologic/ts5300/mainboard.c` had to be adapted manually as no comma was used separating the struct members. And with the following statement, gnomon is even more likable! My pleasure entirely. Good luck with coreboot; I'm a big fan of the project.

2013-02-23AMD based boards: platform_cfg.h: Replace `_*BOARDNAME*_CFG_H_` with ↵Jens Rottmann
`_PLATFORM_CFG_H_` Reduce unnecessary differences between AMD based boards only using the file `platform_cfg.h` for configuration making them a little bit easier to compare. Inagua & co. mention the board name in several places which are really not that board specific. Sometimes people even forget to change it: Union Station’s platform_cfg.h starts with "#ifndef _PERSIMMON_CFG_H_". Funny. Change that to "_PLATFORM_CFG_H_" everywhere. The following command was used. $ find . -name platform_cfg.h | xargs sed -i '/_CFG_H_/s/_.*_/_PLATFORM_CFG_H_/' More boards seem to use that kind of naming (`git grep _CFG_H_`) but it is not certain that this will not break anything as for example the board AMD Dinar also has header files for configuration stuff for the north- and southbridge. $ git grep _CFG_H_ […] src/mainboard/amd/dinar/platform_cfg.h:#ifndef _PLATFORM_CFG_H_ src/mainboard/amd/dinar/platform_cfg.h:#define _PLATFORM_CFG_H_ src/mainboard/amd/dinar/platform_cfg.h:#endif //_PLATFORM_CFG_H_ src/mainboard/amd/dinar/rd890_cfg.h:#ifndef _RD890_CFG_H_ src/mainboard/amd/dinar/rd890_cfg.h:#define _RD890_CFG_H_ src/mainboard/amd/dinar/rd890_cfg.h:#endif //_RD890_CFG_H_ src/mainboard/amd/dinar/sb700_cfg.h:#ifndef _SB700_CFG_H_ src/mainboard/amd/dinar/sb700_cfg.h:#define _SB700_CFG_H_ src/mainboard/amd/dinar/sb700_cfg.h:#endif //_SB700_CFG_H […] Change-Id: Ida15fa6a7adfc770240ac30e795946000dae3f16 Signed-off-by: Jens Rottmann <JRottmann@LiPPERTembedded.de> Signed-off-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-on: http://review.coreboot.org/2464 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martin.roth@se-eng.com>

Adding RTC init code to the Southbridge initialization code in 'late.c'. This initializes the RTC so that the Date Alarm register is set to a valid value (0x00) at startup. By setting the Date Alarm register to 0x00, it does not get evaluated along with the seconds, minutes, and hours when running 'fwts s3'. Information about fwts (Firmware Test Suite) can be found here: https://wiki.ubuntu.com/Kernel/Reference/fwts This was tested on a Persimmon but will apply to other mainboards as well.
