If necessary, SCLEAN needs to run in early romstage, where DRAM is not
working yet. In fact, that the DRAM isn't working is the reason to run
SCLEAN in the first place. Before running GETSEC, CAR needs to be torn
down, as MTRRs have to be reprogrammed to cache the BIOS ACM. Further,
running SCLEAN leaves the system in an undefined state, where the only
sane thing to do is reset the platform. Thus, invoking SCLEAN requires
specific assembly prologue and epilogue sections before and after MTRR
setup, and neither DRAM nor CAR may be relied upon for the MTRR setup.
In order to handle this without duplicating the MTRR setup code, place
it in a macro on a separate file. This needs to be a macro because the
call and return instructions rely on the stack being usable, and it is
not the case for SCLEAN. The MTRR code clobbers many registers, but no
other choice remains when the registers cannot be saved anywhere else.
Tested on Asrock B85M Pro4, BIOS ACM can still be launched.

The MRC will perform PCI enumeration, and if it detects a VGA device in
a PEG slot, it will disable the IGD and not reserve any memory for it.
Since the memory map is locked by the time MRC finishes, the IGD can not
be enabled afterwards. Changing this behavior requires patching the MRC.
Hiding the PEG devices from MRC allows the IGD to be used even when a
dedicated graphics card is present. However, MRC will not program the
PEG AFE settings as it should, which can cause stability problems at
higher PCIe link speeds. Thus, restrict this workaround to only run when
the HASWELL_HIDE_PEG_FROM_MRC option is enabled. This allows the IGD to
be disabled and the PEG AFE settings to be programmed when a dedicated
graphics card is to be enabled, which results in increased stability.
The most ideal way to fix this problem for good is to implement native
platform init. Native init is necessary to make Nvidia Optimus usable.
Tested on Asrock B85M Pro4, using the PEG slot with a dedicated graphics
card as well as without. Graphics in both situations function properly.

SMMSTORE version 2 is a complete redesign of the current driver. It is
not backwards-compatible with version 1, and only one version can be
used at a time.
Key features:
* Uses a fixed communication buffer instead of writing to arbitrary
memory addresses provided by untrusted ring0 code.
* Gives the caller full control over the used data format.
* Splits the store into smaller chunks to allow fault tolerant updates.
* Doesn't provide feedback about the actual read/written bytes, just
returns error or success in registers.
* Returns an error if the requested operation would overflow the
communication buffer.
Separate the SMMSTORE into 64 KiB blocks that can individually be
read/written/erased. To be used by payloads that implement a
FaultTolerant Variable store like TianoCore.
The implementation has been tested against EDK2 master.
An example EDK2 implementation can be found here:

Add an option for unused/reserved bits in a Field definition,
allowing for declarations that do not start at bit 0:
Field (UART, AnyAcc, NoLock, Preserve)
{
, 7, /* RESERVED */
BITF, /* Used bit */
}
These just use byte 0 instead of a name.
