2019-06-06soc/amd/stoneyridge: Relocate MMIO access of ACPI registersMarshall Dawson
The AcpiMmio block allowing direct access to the ACPI registers has remained consistent across AMD models. Move the support from soc//stoneyridge to soc//common.

2019-05-16soc/amd/common: Create AcpiMmio functionality from stoneyridgeMarshall Dawson
Move the stoneyridge AcpiMmio code into soc/amd/common. The SB800 southbridge introduced the MMIO hardware blocks at 0xfed80000 commonly known as AcpiMmio. Implementations beginning with Mullins enable decode in PMx04. Older designs use PMx24 and allow for configuring the base address. Future work may support the older version. Comparing the documentation for AMD's RRGs and BKDGs, it is evident that the block locations have not been reassigned across products. In some cases, address locations are deprecated and new ones consumed, e.g. the early GPIO blocks were simpler at offset 0x100 and the newer GPIO banks are now at 0x1500, 0x1600, and 0x1700. Note: Do not infer the definitions within the hardware blocks are consistent across family/model products.

2019-02-01soc/amd/stoneyridge: Add generic PM1 register clear functionMarshall Dawson
Convert vboot_platform_prepare_reboot() to call a function in soc//stoneyridge. A subsequent patch will add another call to the new function, and this change removes any inference of a dependency on vboot.

2018-10-04amd/stoneyridge: Prepare for vboot rebooting systemMarshall Dawson
Implement the function vboot_platform_prepare_reboot() which is normally a weak function. The SlpTyp field of the PM1 register is not reset to its default value when the APU restarts. This change prevents a failing condition if vboot decides to reset the system instead of allowing an S3 resume to continue. TEST=Resume Grunt when vboot attempts a reset, verify a fresh boot instead BUG=b:117089826 Change-Id: I6e0e3e541bad89ca5b23d6ddb6e5c0df7f762f10 Signed-off-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-on: https://review.coreboot.org/28877 Reviewed-by: Richard Spiegel <richard.spiegel@silverbackltd.com> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2017-09-20vboot: reset vbnv in cmos when cmos failure occursAaron Durbin
There's an occasional issue on machines which use CMOS for their vbnv storage. The machine that just powers up from complete G3 would have had their RTC rail not held up. The contents of vbnv in CMOS could pass the crc8 though the values could be bad. In order to fix this introduce two functions: 1. vbnv_init_cmos() 2. vbnv_cmos_failed() At the start of vboot the CMOS is queried for failure. If there is a failure indicated then the vbnv data is restored from flash backup or reset to known values when there is no flash backup.
