Target added to INTERMEDIATE all operate on coreboot.pre, each modifying
the file in some way. When running them in parallel, coreboot.pre can be
read from and written to in parallel which can corrupt the result.
Add a function to create those rules that also adds existing
INTERMEDIATE targets to enforce an order (as established by evaluation
order of Makefile.inc files).
While at it, also add the addition to the PHONY target so we don't
forget it.

This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION
feature. It's not useful to end-users in this stage so it cannot be
selected in menuconfig (and should not be used other than for
development) yet. With this patch coreboot can verify the metadata hash
of the RO CBFS when it starts booting, but it does not verify individual
files yet. Likewise, verifying RW CBFSes with vboot is not yet
supported.
Verification is bootstrapped from a "metadata hash anchor" structure
that is embedded in the bootblock code and marked by a unique magic
number. This anchor contains both the CBFS metadata hash and a separate
hash for the FMAP which is required to find the primary CBFS. Both are
verified on first use in the bootblock (and halt the system on failure).
The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes
to show some paths that need to be different when full protection
against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For
normal verification it is sufficient to check the FMAP and the CBFS
metadata hash only once in the bootblock -- for TOCTOU verification we
do the same, but we need to be extra careful that we do not re-read the
FMAP or any CBFS metadata in later stages. This is mostly achieved by
depending on the CBFS metadata cache and FMAP cache features, but we
allow for one edge case in case the RW CBFS metadata cache overflows
(which may happen during an RW update and could otherwise no longer be
fixed because mcache size is defined by RO code). This code is added to
demonstrate design intent but won't really matter until RW CBFS
verification can be supported.

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.

cbfs_boot_locate() is supposed to be deprecated eventually, after slowly
migrating all APIs to bypass it. That means common features (like
RO-fallback or measurement) need to be moved to the new
cbfs_boot_lookup().
Also export the function externally. Since it is a low-level API and
most code should use the higher-level loading or mapping functions
instead, put it into a new <cbfs_private.h> to raise the mental barrier
for using this API (this will make more sense once cbfs_boot_locate() is
removed from <cbfs.h>).

This patch adds a new CBFS "mcache" (metadata cache) -- a memory buffer
that stores the headers of all CBFS files. Similar to the existing FMAP
cache, this cache should reduce the amount of SPI accesses we need to do
every boot: rather than having to re-read all CBFS headers from SPI
flash every time we're looking for a file, we can just walk the same
list in this in-memory copy and finally use it to directly access the
flash at the right position for the file data.
This patch adds the code to support the cache but doesn't enable it on
any platform. The next one will turn it on by default.

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.

SMM does not have access to CBMEM and therefore cannot access any
persistent state like the vboot context. This makes it impossible to
query vboot state like the developer mode switch or the currently active
RW CBFS. However some code (namely the PC80 option table) does CBFS
accesses in SMM. This is currently worked around by directly using
cbfs_locate_file_in_region() with the COREBOOT region. By disabling
vboot functions explicitly in SMM, we can get rid of that and use normal
CBFS APIs in this code.

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.

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.

Kconfig 4.17 started using the $(..) syntax for environment variable
expansion while we want to keep expansion to the build system.
Older Kconfig versions (like ours) simply drop the escapes, not
changing the behavior.
While we could let Kconfig expand some of the variables, that only
splits the handling in two places, making debugging harder and
potentially messing with reproducible builds (e.g. when paths end up
in configs), so escape them all.

For AMD's family 17h, verstage can run as a userspace app in the PSP
before the X86 is released. The flags for this have been made generic
to support any other future systems that might run verstage before
the main processor starts.
Although an attempt has been made to make things somewhat generic,
since this is the first and currently only chip to support verstage
before bootblock, there are a number of options which might ultimately
be needed which have currently been left out for simplicity. Examples
of this are:
- PCI is not currently supported - this is currently just a given
instead of making a separate Kconfig option for it.
- The PSP uses an ARM v7 processor, so that's the only processor that
is getting updated for the verstage-before-bootblock option.

This patch improves the response buffer handling for TPM 2.0. Previously
we would allow any command to return no payload, but if there was a
payload we would always try to unmarshal it according to the normal
success response. This was sort of relying on the fact that the TPM
usually returns no additional data after the header for error responses,
but in practice that is not always true. It also means that commands
without a response payload accidentally work by default even though we
did not explicitly add unmarshallig support for them, which seems
undesirable. Adding explicit unmarshalling support for TPM2_SelfTest
which was only supported through this loophole before.
This patch changes the behavior to always accept any amount of payload
data for error responses but not unmarshal any of it. None of our use
cases actually care about payload data for errors, so it seems safer to
not even try to interpret it. For success responses, on the other hand,
we always require support for the command to be explicitly added.
This fixes a problem with the Cr50 GET_BOOT_MODE command where an error
response would only return the subcommand code but no data after that.
Also add support for a second, slightly different NO_SUCH_COMMAND error
code that was added in Cr50 recently.

Similar to bootblock, provide declaration for
verstage_mainboard_early_init() to support early mainboard
initialization if verstage is run before bootblock.

Make vboot verification code accessible in only verstage.
Vboot verification code in vboot_logic.c is being used
in verstage. Due to support function vboot_save_data(),
so core functionality in vboot_logic.c is made available in romstage.
The patch decouples the support function frm vboot_logic.c to
limit itself to verstage.

This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'
