This patch removes all remaining pieces of the old CBFS API, now that
the last straggling use cases of it have been ported to the new one
(meaning cbfs_map()/cbfs_load()/etc... see CB:39304 and CB:38421).

This patch moves the CBFS file measurement when CONFIG_TPM_MEASURED_BOOT
is enabled from the lookup step into the code where a file is actually
loaded or mapped from flash. This has the advantage that CBFS routines
which just look up a file to inspect its metadata (e.g. cbfs_get_size())
do not cause the file to be measured twice. It also removes the existing
inefficiency that files are loaded twice when measurement is enabled
(once to measure and then again when they are used). When CBFS
verification is enabled and uses the same hash algorithm as the TPM, we
are even able to only hash the file a single time and use the result for
both purposes.

High Definition (HD) protected content playback requires secure counters
that are updated at regular interval while the protected content is
playing. To support similar use-cases, define space for secure counters
in TPM NVRAM and initialize them. These counters are defined once during
the factory initialization stage. Also add
VBOOT_DEFINE_WIDEVINE_COUNTERS config item to enable these secure
counters only on the mainboard where they are required/used.

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.

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.

When fetching antirollback information for the kernel, it is not always
known ahead of time what the current size of the kernel secdata area
is. If the incorrect size is passed, the TPM will return back the
correct size, but at the cost of an extra transaction; when using cr50
over I2C, this can be as much as 20ms. Currently, the first attempt uses
the minimium size (aka version 0 or 0.2), and if another size is used
(which is the case for all modern cr50-based boards, version 1 or 1.0),
then a transaction is wasted on every boot.
Therefore, change the default size sent to the TPM to be the default one
used in the VB2 API instead of the minimum one.

vboot_reference is introducing a new field (ctx) to store the current

in both vboot flow and elog_add_boot_reason in coreboot.
In current steps of deciding bootmode, a function vb2ex_ec_trusted

'trusted' only if EC is not in RW. Therefore, we need to implement
similar utilities in coreboot.
We will deprecate vb2ex_ec_trusted and use the flag,
VB2_CONTEXT_EC_TRUSTED, in vboot, vb2api_fw_phase1 and set that flag
in coreboot, verstage_main.
Also add a help function get_ec_is_trusted which needed to be

It can be nice to update the TPM firmware without having to clear the
TPM owner. However, in order to do so would require platformHierarchy
to be enabled which would leave the kernel antirollback space a bit
vulnerable. To protect the kernel antirollback space from being written
to by the OS, we can use the WriteLock command. In order to do so we
need to add the WRITE_STCLEAR TPM attribute.
This commit adds the WRITE_STCLEAR TPM attribute to the rw antirollback
spaces. This includes the kernel antirollback space along with the MRC
space. When an STCLEAR attribute is set, this indicates that the TPM
object will need to be reloaded after any TPM Startup (CLEAR).

On platforms where the boot media can be updated externally, e.g.
using a BMC, add the possibility to enable writes in SMM only. This
allows to protect the BIOS region even without the use of vboot, but
keeps SMMSTORE working for use in payloads. Note that this breaks
flashconsole, since the flash becomes read-only.
Tested on Asrock B85M Pro4 and HP 280 G2, SMM BIOS write protection
works as expected, and SMMSTORE can still be used.

Depending on how the "middle-end" (yes, the gcc developers are
serious about that) optimizer ends up mangling the code, there may
or may not be a complaint about x being used uninitialized when it's
clearly not used at all.
So instead, why keep x in the first place? memcpy(foo, NULL, 0) is
the same as memcpy(foo, some_uninitialized_variable, 0) in that it
does nothing.

We would like to have an easy way to completely disable TPM support on a
board. For boards that don't pre-select a TPM protocol via the
MAINBOARD_HAS_TPMx options, this is already possible with the
USER_NO_TPM option. In order to make this available for all boards, this
patch just removes the whole USER_TPMx option group and directly makes
the TPM1 and TPM2 options visible to menuconfig. The MAINBOARD_HAS_TPMx
options can still be used to select defaults and to prevent selection of
a protocol that the TPM is known to not support, but the NO_TPM option
always remains available.
Also fix some mainboards that selected TPM2 directly, which they're not
supposed to do (that's what MAINBOARD_HAS_TPM2 is for), and add a
missing dependency to TPM_CR50 so it is set correctly for a NO_TPM
scenario.

The new kernel secdata v1 stores the last read EC hash, and reboots the
device during EC software sync when that hash didn't match the currently
active hash on the EC (this is used with TPM_CR50 to support EC-EFS2 and
pretty much a no-op for other devices). Generally, of course the whole
point of secdata is always that it persists across reboots, but with
MOCK_SECDATA we can't do that. Previously we always happened to somewhat
get away with presenting freshly-reinitialized data for MOCK_SECDATA on
every boot, but with the EC hash feature in secdata v1, that would cause
a reboot loop. The simplest solution is to just pretend we're a secdata
v0 device when using MOCK_SECDATA.
This was encountered on using a firmware built with MOCK_SECDATA but had
EC software sync enabled.

refactors the functions slightly to incorporate the vboot context object
such that the correct sizes are used. The various vboot APIs will

The CBFS mcache size default was eyeballed to what should be "hopefully
enough" for most users, but some recent Chrome OS devices have already
hit the limit. Since most current (and probably all future) x86 chipsets
likely have the CAR space to spare, let's just double the size default
for all supporting chipsets right now so that we hopefully won't run
into these issues again any time soon.
The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under
the assumption that Chrome OS images have historically always had a lot
more files in their RO CBFS than the RW (because l10n assets were only
in RO). Unfortunately, this has recently changed with the introduction
of updateable assets. While hopefully not that many boards will need
these, the whole idea is that you won't know whether you need them yet
at the time the RO image is frozen, and mcache layout parameters cannot
be changed in an RW update. So better to use the normal 50/50 split on
Chrome OS devices going forward so we are prepared for the eventuality
of needing RW assets again.
The RW percentage should really also be menuconfig-controllable, because
this is something the user may want to change on the fly depending on
their payload requirements. Move the option to the vboot Kconfigs
because it also kinda belongs there anyway and this makes it fit in
better in menuconfig. (I haven't made the mcache size
menuconfig-controllable because if anyone needs to increase this, they
can just override the default in the chipset Kconfig for everyone using
that chipset, under the assumption that all boards of that chipset have
the same amount of available CAR space and there's no reason not to use
up the available space. This seems more in line with how this would work
on non-x86 platforms that define this directly in their memlayout.ld.)
Also add explicit warnings to both options that they mustn't be changed
in an RW update to an older RO image.

TXT/CBnT, the TPM init needs to happen inside the bootblock to form a
proper chain of trust.

This patch changes the vboot EC sync code to use the new CBFS API. As a
consequence, we have to map the whole EC image file at once (because the
new API doesn't support partial mapping). This should be fine on the
only platform that uses this code (Google_Volteer/_Dedede family)
because they are x86 devices that support direct mapping from flash, but
the code was originally written to more carefully map the file in
smaller steps to be theoretically able to support Arm devices.
EC sync in romstage for devices without memory-mapped flash would be
hard to combine with CBFS verification because there's not enough SRAM
to ever hold the whole file in memory at once, but we can't validate the
file hash until we have loaded the whole file and for performance (or
TOCTOU-safety, if applicable) reasons we wouldn't want to load anything
more than once. The "good" solution for this would be to introduce a
CBFS streaming API can slowly feed chunks of the file into a callback
but in the end still return a "hash valid/invalid" result to the caller.
If use cases like this become pressing in the future, we may have to
implement such an API.
However, for now this code is the only part of coreboot with constraints
like that, it was only ever used on platforms that do support
memory-mapped flash, and due to the new EC-EFS2 model used on more
recent Chrome OS devices we don't currently anticipate this to ever be
needed again. Therefore this patch goes the easier way of just papering
over the problem and punting the work of implementing a more generic
solution until we actually have a real need for it.

RETURN_FROM_VERSTAGE is a somewhat tricky construct that we don't
normally do otherwise in coreboot. While it works remarkably well in
general, new development can lead to unintentional interactions with
confusing results. This patch adds a debug print to the verstage right
before returning to the bootblock so that it's obvious this happens,
because otherwise in some cases the last printout in the verstage is
about some TPM commands which can be misleading when execution hangs
after that point.

The PCR algorithms used for vboot are frequently causing confusion (e.g.
see CB:35645) because depending on the circumstances sometimes a
(zero-extended) SHA1 value is interpreted as a SHA256, and sometimes a
SHA256 is interpreted as a SHA1. We can't really "fix" anything here
because the resulting digests are hardcoded in many generations of
Chromebooks, but we can document and isolate it better to reduce
confusion. This patch adds an explanatory comment and fixes both
algorithms and size passed into the lower-level TPM APIs to their actual
values (whereas it previously still relied on the TPM 1.2 TSS not
checking the algorithm type, and the TPM 2.0 TSS only using the size
value for the TCPA log and not the actual TPM operation).

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 removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.
This patch is the first step of this move, later patches will do the
same for SELFs and other program types.
