Currently, depthcharge and coreboot are using two different vboot libraries.
coreboot is using "fwlib20", while depthcharge uses "fwlib". The only
difference between the two libraries is the inclusion of vboot1-only
compilation units in fwlib, which are now deprecated. Therefore, coreboot
may as well use fwlib too. Vboot is expected to converge on a single firmware
library soon.

Since we already have pre-RAM cache for FMAP (CB:36657), calling
load_firmware() multiple times is no longer a problem. This patch
replaces vboot_get_selected_region() usage with vboot_locate_firmware(),
which locates the firmware by reading from the CBMEM cache.
In addition, returning false from vboot_is_slot_selected() implies the
recovery path was requested, i.e., vb2_shared_data.recovery_reason was
set. Therefore, we simply remove the vboot_is_slot_selected() check from
vboot_check_recovery_request().

The HWID in vboot GBB is an identifier for machine model. On Chrome OS,
that should be provisioned in manufacturing process (by collecting real

For bring up developers, they usually prefer to generate a test-only
string for HWID. However that format was not well documented and cause
problems. Further more, most Chromebooks are using HWID v3+ today while
the test-only HWID is usually v2. Non-Chrome OS developers may also
prefer their own format.
To simplify development process, the GBB_CONFIG now defaults to empty
string, and will be replaced by a board-specific test-only v2 HWID
automatically. Developers can still override that in mainboard Kconfig

With the support of various algorithms and banks in tlcl_extend(),
digest_algo parameter of tpm_extend_pcr() started defining the target
PCR bank in TPM2 case.
The OS expects coreboot to extend the SHA256 bank of BOOT_MODE_PCR.
The value that the OS expects coreboot to extend into BOOT_MODE_PCR
is the SHA1 digest of mode bits extended to the length of SHA256 digest
by appending zero bytes.
Thus the correct value for digest_algo passed into tpm_extend_pcr() for
BOOT_MODE_PCR is TPM_ALG_SHA256.
This didn't matter until adding the support for multiple digest introduced
by patches like https://review.coreboot.org/c/coreboot/+/33252, as
tlcl_extend always used SHA256 bank before.

Add support for Intel PTT. For supporting Intel PTT we need to disable
read and write access to the TPM NVRAM during the bootblock. TPM NVRAM
will only be available once the DRAM is initialized. To circumvent this,
we mock secdata if HAVE_INTEL_PTT is set. The underlying problem is,
that the iTPM only supports a stripped down instruction set while the
Intel ME is not fully booted up. Details can be found in Intel document
number 571993 - Paragraph 2.10.

Add the Command Response Buffer which is defined in the TPM 2.0 Specs.
CRB can be specified with MAINBOARD_HAS_CRB_TPM, even though it is
actually SoC/SB specific.

This reverts commit 598af2e2c2.
Reason for revert: This commit breaks every board with VBOOT enabled
if the platform is apollolake, broadwell, skylake, baswell, baytrails
or icelake. The reason is, that the SoC selects
VBOOT_MUST_REQUEST_DISPLAY by default, and this has a dependency now
on VBOOT_MAY_SKIP_DISPLAY_INIT. This will only be auto-selected if
it is a CHROMEOS platform.

This config option, when set, will allow the platform to skip display
initialization in normal (non-developer, non-recovery) mode. This allows
platforms that do not implement firmware UI in normal mode to skip the
display init in firmware.
TEST=Set option CONFIG_VBOOT and clear CONFIG_VBOOT_MAY_SKIP_DISPLAY_INIT
and the display should initialize in ramstage when platform boots. Set
CONFIG_VBOOT and set CONFIG_VBOOT_MAY_SKIP_DISPLAY_INIT and the display
initialization should be skipped in coreboot.

When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on
some Arm platforms the original working data buffer was in SRAM, which
stays accessbile for the whole runtime of the system. There is no reason
to migrate it into CBMEM on those platforms because ramstage and the
payload could continue to access it in SRAM.
Now that we've had a couple of months of experience with this option, we
found that most of our Arm platforms have some issue that requires
migrating anyway, because BL31 often claims SRAM for itself and makes it
inaccessible to the payload. On the remaining platforms, accessing SRAM
from the payload is possible but still an issue, because libpayload
doesn't have enough memory layout information to set up proper page
tables for it, so we're accessing it uncached and at risk of alignment
errors.
Rather than having to figure out how to map the right SRAM range for
every platform in the payload, let's just get rid of the option.
memcpy()ing 12KB isn't worth this much hassle.
