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.

2017-06-27soc/amd/common: Fix most checkpatch errorsMarshall Dawson
Correct the majority of reported errors and mark most of the remaining ones as todo. Some of the lines requiring a >80 break are indented too much currently. Changes to agesawrapper.c cause the build to change, so this file is also left as-is. Make hex values consistently lower-case.
