This reverts commit 9ff4029db9.
Pulling the toplevel Makefile into a tiny one has all sorts of side
effects. For instance, the toplevel (random) .config is also included
so the results depend on the board that is selected there. What finally
broke it is a line that is unconditionally printed for AMD Picasso
boards resulting in lots of lines like this:
skipping LENOVO_W520 because we're missing compilers for \
(Adding PSP c7ce61492157d3237f679c4a40a08b79 \
.../coreboot/3rdparty/amd_blobs/picasso/PSP/PspBootLoader_prod_RV.sbin)
While both issues, the random .config and amd/picasso, could be worked
around easily, it seems hard to predict what other pitfalls are lurking
in the Makefile inclusion. Also, the problem solved by its inclusion
can be fixed by a much simpler `make .xcompile`.

Picasso doesn't really make use of the common mrc_cache driver because
of the PSP/ABL requirements for APOB NV data. The APOB NV data
gets consumed by PSP/ABLs before x86 comes out of reset. Hence, we cannot
really add any metadata to this saved data or use multiple slots as
done by the default MRC cache driver
(CACHE_MRC_SETTINGS). Additionally, FSP-M requires access to this APOB
NV data which coreboot needs to pass in from different locations
depending upon boot mode:
1. Non-S3 boot: PSP/ABLs store APOB NV data in DRAM at predetermined
location which is present in BIOS directory table.
2. S3 boot: PSP/ABLs do not store APOB NV data in DRAM.
Thus, coreboot needs to set FSP-M UPD NvsBufferPtr as the DRAM
location in non-S3 boot and the address of RW_MRC_CACHE on SPI flash
in case of S3 resume.
This change enables MRC cache support in Picasso in order to meet the
above requirements.
1. NvsBufferPtr is set based on boot mode.
2. APOB NV data is not stashed to CBMEM. Instead it is written right
away to SPI flash in romstage.

on S0ix exit.
This patch adds the following three platform specific methods.
1. MS0X to enable power management features for GPIO communities on

2. MPTS to enable power management features for GPIO communities when

3. MWAK to disable power management features for GPIO communities on
