2018-04-13soc/amd/stoneyridge: add a romstage hook for mainboardsMartin Roth
There wasn't previously a way for Stoney platforms to run mainboard specific code in romstage. This adds an early call for configuration and passes along whether the system is currently resuming from S3. BUG=b:77921345 TEST=Build, verify that weak function implementation gets called.

2017-11-13soc/amd/stoneyridge: Fix DRAM clear checkMarshall Dawson
Explicitly add #include files to romstage.c to ensure sizes of the devicetree structures are correct. The AMD support headers have an open #pragma pack(1) which causes structure sizes to change based on include ordering in different compilation units. More concretely, this fixes a bug where dev->chip_info is incorrectly detected as 0. Also shorten a printk string to bring the source line within 80 columns.

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: Convert MP init to mp_init_with_smmMarshall Dawson
Change the Stoney Ridge SOC to a more modern method for setting up the multiple cores. Add a new cpu.c file for most of the processor initiliazation. Build mp_ops with the necessary callbacks. Note also that this patch removes cpu_bus_scan. Rather than manually find CPUs and add them to the devicetree, allow this to be done automatically in the generic mp_init.c file. SMM information is left blank in mp_ops to avoid having mp_init.c install a handler at this time. A later patch will add TSEG SMM capabilities for the APU. This patch also contains a hack to mask the behavior of AGESA which configures the MTRRs and Tom2ForceMemTypeWB coming out of AmdInitPost. The hack immediately changes all WB variable MTRRs, on the BSP, to UC so that all writes to memory space will make it to the DRAM.

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.
