2017-07-27	soc/amd/common: Convert to C_ENVIRONMENT_BOOTBLOCK	Marshall 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.

2017-07-02	soc/amd/common: Add initial support for AMD PSP	Marshall 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.

2017-06-29	soc/amd/stoneyridge: Convert monotonic timer	Marshall Dawson
	Use the TSC for the Stoney Ridge monotonic timer. Modern AMD CPUs have invariant timestamp counters. This patch brings the feature more in line with other devices and allows the use of typical monotonic timer functions.
