Intel Meteor Lake decides to enable early caching of the TOM region to
optimize the boot time by selecting `SOC_INTEL_COMMON_BASECODE_TOM`
config.
TEST=Able to build and boot google/rex to ChromeOS and reduce the boot
time by 77 ms.

This patch implements a module that can store the top_of_ram (TOM)
address into non-volatile space (CMOS) during the first boot and
use it across all consecutive boot.
As top_of_ram address is not known until FSP-M has exited, it
results into lacking of MTRR programming to cache the 16 MB TOM,
hence accessing that range during FSP-M and/or late romstage causing
long access times.
Purpose of this driver code is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).

When cbmem is initialized in romstage and postcar placed in the stage
cache + cbmem where it is run, the assumption is made that these are
all in UC memory such that calling INVD in postcar is OK.
For performance reasons (e.g. postcar decompression) it is desirable
to cache cbmem and the stage cache during romstage.
Another reason is that AGESA sets up MTRR during romstage to cache all
dram, which is currently worked around by using additional MTRR's to
make that UC.
TESTED on asus/p5ql-em, up/squared on both regular and S3 resume
bootpath. Sometimes there are minimal performance improvements
when cbmem is cached (few ms).

This separates the SPL fusing function into a separate C file which can
be excluded if it is not needed. This allows the psp_set_spl_fuse()
function to be made static again as the state of the function will
always match the boot_state entry.
Move the required #defines to the common header file so they can be
used by both psp_gen2.c & spl_fuse.c.

Even though right now TSEG will always be located below 4GB, better not
make assumptions in the SMM relocation code. Instead of clearing the
higher 32 bits and just assigning the TSEG base and per-core SMM base to
the lower 32 bits of the MSR, assign those two base addresses to the raw
64 bit MSR value to not truncate the base addresses. Since TSEG will
realistically never be larger than 4GB and it needs to be aligned to its
power-of-two size, the TSEG mask still only needs to affect the lower
half of the corresponding MSR value.

of PSP, and fill the combo header. Currently Feature COMBO is still

1. Add a do-while loop.
2. Remove a "TODO" comment.

For simplicity, OEM devices are given a single codename per build variant. Winterhold was intended to be the lead device and was chosen as the code name for this OEM. Unfortunately, Winterhold was cancelled. We attempted to rename Winterhold to Whiterun to avoid future confusion. Again, unfortunately, since some devices were already built, changing the name requires a manual change to force the firmware to be taken by the DUT. This was not a reasonable path forward, so we're abandoning the naming to Whiterun.

Picasso already uses the Cxxx ACPI CPU device naming scheme, due to it
being what the AGESA reference code uses. We initially relied on the
AGESA/FSP generated SSDT for the P- and C-state support before we had a
native implementation for this in coreboot. The Cxxx naming scheme can
also be used for the other AMD SoCs except Stoneyridge which is pre-Zen
and doesn't select SOC_AMD_COMMON_BLOCK_NONCAR. The main advantage of
using Cxxx instead of CPxx is that the Cxxx scheme supports systems with
more than 256 CPU threads.

This reverts commit b42ca4d0b2.
Reason for revert: The mirror flag "0x01" is mirror once, which
relies on the EC remembering that it's been mirrored. However, the
EC forgets this if it's been without power for 20 minutes or so.
Even if power is connected then, it'll instantly try to mirror and
it can't charge whilst doing it. It can either result in
incomplete EC firmware, or a loop where it's constantly trying to
mirror.
