Some processor families allow for SMM setup to be done in parallel.
On processors that have this feature, the BIOS resource list becomes
unusable for some processors during STM startup.
This patch covers two cases: (1) The BIOS resource list becomes twice
as long because the smm_relocation function is called twice - this is
resolved by recreating the list on each invocation. (2) Not all
processors receive the correct resource list pointer - this is resolved
by having every processor execute the pointer calculation code, which is
a lot faster then forcing all processors to spin lock waiting for this
value to be calculated.
This patch has been tested on a Purism L1UM-1X8C and Purism 15v4.

Since we may have either BIOS ACM or both BIOS and SINIT ACMs in CBFS,
the size of txt_heap_acm_element will be different. We cannot always
hardcode the size of ACM addresses array for two ACMs. If only the BIOS
ACM was included, the BDR parsing failed in TBoot due to invalid size
of HEAP_ACM element. Check if SINIT ACM is present in CBFS and push
properly formatted BDR region onto the TXT heap. Use two separate
txt_heap_acm_element structures with different lengths.
TEST=Boot QubesOS 4.0 with TBoot 1.8.2 on Dell OptiPlex 9010 with and

IA32_FEATURE_CONTROL does not need to be checked by BIOS, in fact these
bits are needed only by SENTER and SINIT ACM. ACM ENTERACCS does not
check these bits according to Intel SDM. Also noticed that the lock bit
of IA32_FEATURE_CONTROL cannot be cleared by issuing neither global
reset nor full reset on Sandybridge/Ivybridge platforms which results
in a reset loop. However, check the IA32_FEATURE_CONTROL SENTER bits in
ramstage where the register is properly set on all cores already.

Access mechanism (ECAM) method for accessing the PCI config address
space. Some platforms have a different way of mapping the PCI config
space to memory. This patch renames the following configs to
make it clear that these configs are ECAM-specific:
- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH

With CBnT a digest needs to be made of the IBB, Initial BootBlock, in
this case the bootblock. After that a pointer to the BPM, Boot Policy
Manifest, containing the IBB digest needs to be added to the FIT
table.
If the fit table is inside the IBB, updating it with a pointer to the
BPM, would make the digest invalid.
The proper solution is to move the FIT table out of the bootblock.
The FIT table itself does not need to be covered by the digest as it
just contains pointers to structures that can by verified by the
hardware itself, such as microcode and ACMs (Authenticated Code
Modules).

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

Provide necessary romstage hooks to allow unblocking the memory with
SCLEAN. Note that this is slow, and took four minutes with 4 GiB of RAM.
Tested on Asrock B85M Pro4 with tboot. When Linux has tboot support
compiled in, booting as well as S3 suspend and resume are functional.
However, SINIT will TXT reset when the iGPU is enabled, and using a dGPU
will result in DMAR-related problems as soon as the IOMMU is enabled.
However, SCLEAN seems to hang sometimes. This may be because the AP
initialization that reference code does before SCLEAN is missing, but
the ACM is still able to unblock the memory. Considering that SCLEAN is
critical to recover an otherwise-bricked platform but is hardly ever
necessary, prefer having a partially-working solution over none at all.

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.

This allows platform code to program the size in the MCH DPR register.

Due to platform-specific constraints, it is not possible to enable DPR
by programming the MCH's DPR register in ramstage. Instead, assume it
has been programmed earlier and check that its value is valid. If it is,
then simply configure DPR in TXT public base with the same parameters.
Note that some bits only exist on MCH DPR, and thus need to be cleared.
Implement this function on most client platforms. For Skylake and newer,
place it in common System Agent code. Also implement it for Haswell, for
which the rest of Intel TXT support will be added in subsequent commits.
Do not error out if DPR is larger than expected. On some platforms, such
as Haswell, MRC decides the size of DPR, and cannot be changed easily.
Reimplementing MRC is easier than working around its limitations anyway.

The BIOS ACM will check that enabled variable MTRRs do not cover more
than the ACM's size, rounded up to 4 KiB. If that is not the case,
launching the ACM will result in a lovely TXT reset. How boring.
The new algorithm simply performs a reverse bit scan in a loop, and
allocates one MTRR for each set bit in the rounded-up size to cache.
Before allocating anything, it checks if there are enough variable
MTRRs; if not, it will refuse to cache anything. This will result in
another TXT reset, initiated by the processor, with error type 5:
Load memory type error in Authenticated Code Execution Area.
This can only happen if the ACM has specific caching requirements that
the current code does not know about, or something has been compromised.
Therefore, causing a TXT reset should be a reasonable enough approach.
Also, disable all MTRRs before clearing the variable MTRRs and only
enable them again once they have been set up with the new values.
Tested on Asrock B85M Pro4 with a BIOS ACM whose size is 101504 bytes.
Without this patch, launching the ACM would result in a TXT reset. This
no longer happens when this patch is applied.

When caching the BIOS ACM, one must cache less than a page (4 KiB) of
unused memory past the end of the BIOS ACM. Failure to do so on Haswell
will result in a lovely TXT reset with Class Code 5, Major Error Code 2.
The current approach uses a single variable MTRR to cache the whole BIOS
ACM. Before fighting with the variable MTRRs in assembly code, ensure
that enough variable MTRRs exist to cache the BIOS ACM's size. Since the
code checks that the ACM base is aligned to its size, each `one` bit in
the ACM size will require one variable MTRR to properly cache the ACM.
One of the several BIOS ACMs for Haswell has a size of 101504 bytes.
This is 0x18c80 in hexadecimal, and 0001 1000 1100 1000 0000 in binary.
After aligning up the BIOS ACM size to a page boundary, the resulting
size is 0x19000 in hexadecimal, and 0001 1001 0000 0000 0000 in binary.
To successfully invoke said ACM, its base must be a multiple of 0x20000
and three variable MTRRs must be used to cache the ACM. The MTRR ranges
must be contiguous and cover 0x10000, 0x8000, 0x1000 bytes, in order.
The assembly code is updated in a follow-up, and relies on these checks.

Size_t seems to have a compiler dependency. When building on the
Purism librem 15v4, size_t is 'unsigned long'. In this instance,
the compiler is the coreboot configured cross-compiler. In another
instance, size_t is defined as 'unsigned short'. To get around
the formatting conflict caused by this, The variable of type
size_t was cast as 'unsigned int' in the format.

The MSR macros were treated as memory addresses and the loops had
off-by-one errors. This resulted in a CPU exception before GETSEC, and
another exception after GETSEC (once the first exception was fixed).
Tested on Asrock B85M Pro4, ACM complains about the missing TPM and
resets the platform. When the `getsec` instruction is commented-out, the
board is able to boot normally, without any exceptions nor corruption.
