2018-01-19amd/common: Define regions in AGESA cbmemMarshall Dawson
In 6c747068 "amd/stoneyridge: Put AGESA heap into cbmem" the AGESA heap was moved completely into cbmem. This was a departure from the "late cbmem init" method of adding it late in post, then storing the S3 volatile data to the region. Remove the hardcoded base address that was missed in that commit. To prepare for S3 support, split the region into subregions for heap, AGESA's S3 volatile storage, and an MTRR save area.

2018-01-12soc/amd/common/pi: Fix issue in AGESA heap allocatorMarc Jones
The heap allocator would try to split a buffer node that was too small for another node. In the failing case, the buffer node was 0x140 bytes and the requested size was 0x133 bytes. The logic would check that there was room for the header and buffer and try to split the buffer node. The buffer node header is 0xC bytes, so 0x13F bytes are need. The problem is that it didn't leave room for another node header and a little space for a buffer. BUG=b:71764350 TEST= Boot grunt.

Change the cache-as-ram teardown to use invd instead of wbinvd. Save the return and recover the call's return address in chipset_teardown_car. CAR teardown had been modified to use wbinvd to send CAR contents to DRAM backing prior to teardown. This allowed CAR variables, stack, and local variables to be preserved while running the AMD_DISABLE_STACK macro. Using the wbinvd instruction has the side effect of sending all dirty cache contents to DRAM and not only our CAR data. This would likely cause corruption, e.g. during S3 resume. Stoney Ridge now uses a postcar stage and this is no longer a requirement.

Insert a postcar stage for Stoney Ridge and move romstage's CAR teardown there. The AMD cache-as-ram teardown procedure currently uses a wbinvd instruction to send CAR contents to DRAM backing. This allows preserving stack contents and CAR globals after the teardown happens, but likely results in memory corruption during S3 resume. Due to the current base of the DCACHE region, reverting to an invd instruction will break the detection mechanism for CAR migrated variables. Using postcar avoids this problem. The current behavior of AGESA is to set up all cores' MTRRs during the AmdInitPost() entry point. This implementation takes control back and causes postcar's _start to clear all settings and set attributes only for the BIOS flash device, TSEG, and enough space below cbmem_top to load and run ramstage.

2017-08-28soc/amd: Standardize guards on header filesMartin Roth
The guards in the header files were inconsistent. Some had no leading or trailing underscores, some had one, some had both leading and trailing. Change all to double leading & trailing underscores. Change all comments to have a space before them instead of tabs BUG=b:62235990 Test=Build Kahlee Change-Id: I4466df529ab201c922096a31d7438381778b582f Signed-off-by: Martin Roth <martinroth@google.com> Reviewed-on: https://review.coreboot.org/21073 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Marc Jones <marc@marcjonesconsulting.com> Reviewed-by: Marshall Dawson <marshalldawson3rd@gmail.com>
2017-07-27soc/amd/common: Convert to C_ENVIRONMENT_BOOTBLOCKMarshall Dawson
Add dedicated CAR setup and teardown functions and Kconfig options to force their inclusion into the build. The .S files are mostly duplicated code from the old cache_as_ram.inc file. The .S files use global proc names in anticipation for use with the Kconfig symbols C_ENVIRONMENT_BOOTBLOCK and POSTCAR_STAGE. Move the mainboard romstage functionality into the soc directory and change the function name to be compatible with the call from assembly_entry.S. Drop the BIST check like other devices. Move InitReset and InitEarly to bootblock. These AGESA entry points set some default settings, and release/recapture the AP cores. There are currently some early dependencies on InitReset. Future work should include: * Pull the necessary functionality from InitReset into bootblock * Move InitReset and InitEarly to car_stage_entry() and out of bootblock - Add a mechanism for the BSP to give the APs an address to call and skip most of bootblock and verstage (when available) (1) - Reunify BiosCallOuts.c and OemCustomize.c (1) During the InitReset call, the BSP enables the APs by setting core enable bits in F18F0x1DC and APs begin fetching/executing from the reset vector. The BSP waits for all APs to also reach InitReset, where they enter an endless loop. The BSP sends a command to them to execute a HLT instruction and the BSP eventually returns from InitReset. The goal would be to preserve this process but prevent APs from rerunning early code.

2017-07-02soc/amd/common: Add initial support for AMD PSPMarshall Dawson
Add files for supporting the BIOS->PSP communication not covered by AGESA. The first command implemented notifies the PSP that DRAM is ready. This patch also introduces the amd/common/block directory structure similar to intel/common/block.
