2017-09-30soc/amd/common: Add included directoryMarshall Dawson
If the symbol SOC_AMD_COMMON is selected, include the soc/amd/common directory. Until now this has been working due to the directory being included as part of AGESA_INC in vendorcode. That one is still necessary in order to build the AGESA code so it is left in place for now.

2017-09-27soc/amd/stoneyridge: Revert CAR teardown wbinvdMarshall Dawson
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.

2017-09-27soc/amd/stoneyridge: Add postcar stageMarshall Dawson
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.

2017-09-27amd/stoneyridge: Put AGESA heap into cbmemMarshall Dawson
Now that soc/amd supports EARLY_CBMEM_INIT, put the HEAP into cbmem, allowing better control of its cacheability in subsequent patches. This relocates the heap initialization from the common directory into a romstage cbmem hook. The conversion relies on cbmem_add() first searching cbmem for the ID before adding a new entry.

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.
