Originally, this patch made 'BIOS' uppercase in the referenced comment
and converted the C++ style to be consistent with the remainder of
the function. Somewhere, the 'BIOS' became uppercase creating a merge
conflict.
Now this CL converts the C++ style to be consistent with the remainder
of the comments.

FSP-T takes microcode pointer and location parameters, and FSP-T is
invoked before CAR is set-up and before memory is trained. So it is not
possible to modify supplied microcode pointer in runtime. Because of
that we have to hardcode the pointer in bootblock.
Also, current FSP-T on Xeons require microcode (it is not optional).
Reasons for that are currently unclear and are being investigated.
However for the present time we need to be able to add microcode at a
certain offset so FSP-T can be used.

This is done to facilitate the report_platform_info to be called from

This update is a combination of all four of the patches so that the
commit can be done without breaking parts of coreboot. This possible
breakage is because of the cross-dependencies between the original
separate patches would cause failure because of data structure changes.
security/intel/stm
This directory contains the functions that check and move the STM to the
MSEG, create its page tables, and create the BIOS resource list.
The STM page tables is a six page region located in the MSEG and are
pointed to by the CR3 Offset field in the MSEG header. The initial
page tables will identity map all memory between 0-4G. The STM starts
in IA32e mode, which requires page tables to exist at startup.
The BIOS resource list defines the resources that the SMI Handler is
allowed to access. This includes the SMM memory area where the SMI
handler resides and other resources such as I/O devices. The STM uses
the BIOS resource list to restrict the SMI handler's accesses.
The BIOS resource list is currently located in the same area as the
SMI handler. This location is shown in the comment section before
smm_load_module in smm_module_loader.c
Note: The files within security/intel/stm come directly from their
Tianocore counterparts. Unnecessary code has been removed and the
remaining code has been converted to meet coreboot coding requirements.

The current MP init timeout is hardcoded as 1s. To support
platform with many cpus, the timeout needs to be adjusted.
The number of cpus is calculated as:
number of sockets * number of cores per socket *
number of threads per core
How long the timeout should be set to, is heuristic.
It needs to be set long enough to ensure reboot stability,
but not unreasonable so that real failures can be detected
soon enough, especially for smaller systems.
This patch sets timeout to be minimum as 1 second, while each
cpu adds 0.1 second.

It was possible to have NO_STAGE_CACHE=n and at the same time have
TSEG_STAGE_CACHE=n and CBMEM_STAGE_CACHE=n. This resulted with a
failing attempt to load STAGE_POSTCAR from the stage cache, but not
loading it from CBFS either.
Make it a three-way choice between different STAGE_CACHE options.
For AGESA disable CBMEM_STAGE_CACHE by default, as it is no longer
needed to have functional ACPI S3 resume and it is not allowed
se use keyword select for symbols inside choice blocks.

If a board doesn't want to provide it, it has to select NO_FMAP_CACHE.
Adding FMAP_CACHE regions to a couple more targets that I think can use
them but I don't know anything about... please yell if one of these is
a bad idea and I should mark them NO_FMAP_CACHE instead.
