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.

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.

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.

Simplify funciton names and remove reference to hudson in stoneyridge.
The southbridge in Stoney Ridge is Kern and hudson naming is
no longer accurate.

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.

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().

Copy the Hudson/Kern code from southbridge/amd/pi/hudson. This
is the first of a series of patches to migrate Stoney Ridge
support from cpu, northbridge, and southbridge to soc/
Changes:
- add soc/amd/stoneyridge and soc/amd/common
- remove all other Husdon versions
- update include paths, etc
- clean up Kconfig and Makefile
- create chip.c to contain chip_ops
