6f8e9443aa security/tpm: Add option to init TPM in bootblock
When using a hardware assisted root of trust measurement, like Intel
TXT/CBnT, the TPM init needs to happen inside the bootblock to form a
proper chain of trust.

0d9072b1a1 cbfs: Move more stuff into cbfs_boot_lookup()
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>).

dcae8074bf drivers/spi/tpm: Enable long cr50 ready pulses for Tiger Lake systems
For Volteer (and future Tiger Lake boards) we can enable mode S0i3.4
only if we know that the Cr50 is generating 100us interrupt pulses.
We have to do so, because the SoC is not guaranteed to detect pulses
shorter than 100us in S0i3.4 substate.

A new Kconfig setting CR50_USE_LONG_INTERRUPT_PULSES controls new code
running in verstage, which will program a new Cr50 register, provided that
Cr50 firmware is new enough to support the register.

71a131415e security: tcg-2.0: Ignore data payload for errors, fix Cr50 boot mode
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.

23a82e87ee security/tpm: Fix compile-time elimination for SEPARATE_VERSTAGE
CB:35077 pulled TPM measurement code into the bootblock, with the catch
that we'll only cache PCR extensions and not actually write them to the
TPM until it gets initialized in a later stage. The goal of this was to
keep the heavy TPM driver code out of the size-constrained bootblock.

Unfortunately, a small mistake in the tspi_tpm_is_setup() function
prevents the compiler from eliminating references to the TPM driver
code in the bootblock on platforms with CONFIG_VBOOT and
CONFIG_SEPARATE_VERSTAGE. In those cases vboot_logic_executed() is known
at compile-time to be 0, but that still makes the final expression
`return 0 || tpm_is_setup;`. We know that tpm_is_setup can never be set
to 1 in the bootblock, but the compiler doesn't.

This patch rewrites the logic slightly to achieve the same effect in a
way that the compiler can follow (because we only really need to check
tpm_is_setup in the stage that actually runs the vboot code).

c79e96b4eb security/vboot: Decouple measured boot from verified boot
Currently, those who want to use measured boot implemented within
vboot should enable verified boot first, along with sections such
as GBB and RW slots defined with manually written fmd files, even
if they do not actually want to verify anything.

As discussed in CB:34977, measured boot should be decoupled from
verified boot and make them two fully independent options. Crypto
routines necessary for measurement could be reused, and TPM and CRTM
init should be done somewhere other than vboot_logic_executed() if
verified boot is not enabled.

In this revision, only TCPA log is initialized during bootblock.
Before TPM gets set up, digests are not measured into tpm immediately,
but cached in TCPA log, and measured into determined PCRs right after
TPM is up.

This change allows those who do not want to use the verified boot
scheme implemented by vboot as well as its requirement of a more
complex partition scheme designed for chromeos to make use of the
measured boot functionality implemented within vboot library to
measure the boot process.

f3f36faf35 src (minus soc and mainboard): Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

31b7ee4201 treewide: Replace uses of "Nehalem"
The code in coreboot is actually for the Arrandale processors, which
are a MCM (Multi-Chip Module) with two different dies:

- Hillel:   32nm Westmere dual-core CPU
- Ironlake: 45nm northbridge with integrated graphics

This has nothing to do with the older, single-die Nehalem processors.
Therefore, replace the references to Nehalem with the correct names.

6d5fcf4fbe security/tpm: Add a Kconfig to disregard INVALID_POSTINIT on startup
There are use cases where TPM has already been set up in a previous
stage, e.g. TXT or when a CPU reset without a platform reset happens.
If this is the case the TPM startup will return a
INVALID_POSTINIT (return code 0x26). This adds a Kconfig to allow
platforms to disregard that return code.

b3426c03b4 Revert "security/tpm/tss/tcg-2.0: Add multi digits support to tlcl_extend()"
This reverts commit fdb9805d68.

CB:33252 wasn't reviewed by a TPM maintainer and breaks abstraction
layers (pulling TSS-details into TSPI, completely changing
interpretation of the arguments to tlcl_extend() based on TSS version).
It's also not clear why it was implemented the way it was (should have
been much easier and cleaner ways to achieve the same thing).

Since the author is not reacting, let's revert it for now. It can be
cleaned up and resubmitted later. (Not reverting the header changes
since those are not objectionable, and there are later patches dependent
on it.)

TPMU_HA is a union of all the different hash digests, and so
sizeof(TPMU_HA) evaluates to 64 (the size of the largest one). This will
lead to out-of-bounds writes when copying smaller digests, so use the
specific digest size for each algorithm.
