If a platform does verification of the memory init step, and it must
resume with the same slot that it booted from then it needs to set
the vboot context flag when resuming instead of booting. This will
affect the slot that is selected to verify and resume from.

This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.
For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

vboot during the boot flow. Therefore, it's important that the first call to

Add a wrapper around the vbnv implementations and call into the different
backend functions from there. Also move some of the common functions to
the common code and simplify the backend drivers. This will allow some
of the code to be re-used so the CMOS backend can backup the data into
the flash backend.
One side effect of this is that the cache of VBNV was removed from CMOS
and EC backends and moved into the VBNV wrapper, but the flash backend
also still has a separate cache because it has more state and complexity
in the implementation. The wrapper cached data is not used for normal
vbnv_read/vbnv_write because some callers need the ability to force a
write if the backend storage is cleared (i.e. CMOS clear).

For x86 systems which resume through the reset vector one needs to
ensure the the RW slot taken at resume time matches the one at
boot time. The reason is that any assets pulled out of the boot
media need to match how the platform previously booted. To do
that one needs obtain the hash digest of the chosen slot, and it
needs to be saved in a secure place on the normal boot path. On
resume one needs to retrieve the hash digest back to compare it
with the chosen slot. If they don't match resuming won't be

There are few drawbacks reading VPD from SPI flash in user land, including

Since for many platforms we are already reading VPD in firmware (for

While migrating from vboot1 to vboot2, the tpm_init was moved out of
vboot library and implemented in coreboot. However, while doing this,
the initial factory flow was missed.
We need to ensure following flow for tpm_init:
1. Perform tpm_init
2. If tpm_init fails, set secdata_context flag to indicate to vboot
that tpm needs reboot.
3. Call vb2_api_phase1
4. If vb2_api_phase1 returns error code saying boot into recovery,
continue booting into recovery. For all other error codes, save
context if required and reboot.

vboot handoff should look at flags in struct vb2_shared_data when
translating flags to VBSD_BOOT_REC_SWITCH_ON because
VBSD_BOOT_REC_SWITCH_ON is supposed to indicate whether manual recovery was
triggered or not while vb2_sd->recovery_reason will be able to provide
that information only in some cases after CL:307586 is checked in.
For example, this fixes a recovery loop problem: Without this fix,
vb2_sd->recovery_reason won't be set to VB2_RECOVERY_RO_MANUAL when user
hits esc+refresh+power at 'broken' screen. In the next boot,
recovery_reason will be set to whatever reason which caused 'broken'
screen. So, if we check recovery_reason == VB2_RECOVERY_RO_MANUAL, we
won't set vb_sd->flags to VBSD_BOOT_REC_SWITCH_ON. That'll cause a
recovery loop because VbBootRecovery traps us again in the 'broken'
screen after not seeing VBSD_BOOT_REC_SWITCH_ON.

To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

In order to support x86 verstage proper the work buffer
needs to live in cache-as-ram. However, after cache-as-ram
is torn down one still needs the verification results to
know which slot was selected. Though the platforms with
a dedicated SRAM can just use the work buffer in SRAM, the
x86 cache-as-ram platforms need a place to stash the
results. For that situation cbmem is employed. This works
because when cbmem is initialized cache-as-ram is still
enabled. The VBOOT_DYNAMIC_WORK_BUFFER case assumes
verified boot doesn't start until after cbmem is up. That
doesn't change, but it's a goal to get rid of that option
entirely once all other x86 platforms are moved over to
pre-romstage vboot.

Up to now, the multi-CBFS code path merely looked up files in the "boot
ro" image (ie. the default), disregarding the specified fmap region to
use for CBFS.
The code still relies on the master header being around, which on the
upside allows it to skip an offset at the beginning of the region (eg.
for ARM bootblocks).
This will change later (both the reliance on the master header and the
presence of the bootblock like this).

This moves a few vboot-prefixed functions that were defined in chromeos.c to
vboot_common.c, since those are only relevant to vboot and depend on the vboot
handoff data. This allows more separation between CONFIG_CHROMEOS and what
CONFIG_CHROMEOS selects, so that each separate option (such as
CONFIG_VBOOT_VERIFY_FIRMWARE) can be enabled separately.
Thus, the actual definitions of these functions will only be declared when
CONFIG_VBOOT_VERIFY_FIRMWARE is set, so the check before calling
vboot_skip_display_init in bootmode was also adapted.
