2017-12-12soc/amd/common: Move Agesa related headersRichard Spiegel
Move AGESA related headers in soc/amd/common to soc/amd/common/block/include/amdblocks. BUG=b:69262110 TEST=Build with no error gardenia and kahlee (no code change, headers moved).

2017-11-14soc/amd/stoneyridge: Load SMU fimware using PSPMarshall Dawson
Add the ability to locate the SMRAM-based SMU firmware early and call the PSP library to load it prior to DRAM initialization. This is currently placed in bootblock to ensure the blob is loaded before any reset occurs. Add similar functionality in ramstage for SMU FW2 to the hook already in place for running AmdInitEnv. Rename the hook to make more sense. This patch was tested using a pre-released PSP bootloader on a google/kahlee system. Leave the option unused until the bootloader is ready.

2017-11-08amd/stoneyridge: Remove fixme.cMarshall Dawson
Move the two functions in fixme.c to places where they make more sense. Coincidentally fix the todo in amd_initcpuio() and use bsp_topmem() instead of explicitely reading the MSR.

2017-10-16soc/amd/stoneyridge: Check UART indexMarshall Dawson
The Stoney Ridge APU has only two internal UARTs. Add checks for invalid settings. When enabling the UART, return if the console is on any UART not equal 0 or 1. The base address returned is 0 if an invalid configuration is used. All callers check the return value before using the returned value. Finally, provide an assert at the earliest availability of the console to get the notice into the cbmem console. BUG=b:62201567 TEST=Build with UART = -1, 0, 2. Inspect objdump and boot to OS. Build without ST UART and inspect with objdump.

2017-08-14stoneyridge: Rename hudson to southbridgeMarc Jones
Simplify funciton names and remove reference to hudson in stoneyridge. The southbridge in Stoney Ridge is Kern and hudson naming is no longer accurate.

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/stoneyridge: 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.) Some of the alignment in hudson.h still causes checkpatch errors, but this is intentionally left as-is. Also make other misc. changes, e.g. consistency in lower-case for hex values, using defined values, etc. These changes were confirmed to cause no changes in a Gardenia build. No other improvements were made, e.g. changing to helper functions, or converting functions like __outbyte().
