Aaron Durbin ee049fa802 drivers/i2c/tpm: use iobuf library for marshaling commands
Use the iobuf API instead of relying on own buffer management. It
also provides consistency between marshaling and unmarshaling code
paths for propagating return values instead of overloading the values
of existing variables.

Julius Werner d67c6876b5 Turn CBMEM console into a ring buffer that can persist across reboots
This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)

The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).

There's a missing closing brace in fillbits function of jpeg.c which

Julius Werner e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

Julius Werner 58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

Vadim Bendebury 021ec2819b cr50: add unmarshaling of vendor commands and process 'enable_update'
The upcoming Cr50 firmware changes will require the AP to enable the
previously downloaded Cr50 firmware update(s).

A new vendor command (TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for
that. The command accepts one parameter - a timeout value in range of
0 to 1000 ms.

When processing the command the Cr50 checks if the alternative RO or
RW image(s) need to be enabled, and if so - enables them and returns
to the host the number of enabled headers.

If the vendor command requested a non-zero timeout, the Cr50 starts
a timer to trigger system reboot after the requested timeout expires.

The host acts on the number of enabled headers - if the number is
nonzero, the host prepares the device to be reset and waits for the
Cr50 to reboot the device after timeout expires.

This patch also adds more formal vendor command
marshaling/unmarshaling to make future additions easier.

BRANCH=gru,reef
BUG=b:35580805
TEST=with the actual user of this code in the next patch verified that
     the cr50 update is enabled as expected.

Aaron Durbin eeb77379e0 vboot/tpm2: enable nvmem commits on cr50 when writing firmware secdata
cr50 by default delays nvmem commits internally from the point of
reset to accumulate change state. However, the factory process can
put a board into dev mode through the recovery screen. This state
is stored in the TPM's nvmem space. When the factory process is
complete a disable_dev_request and battery_cutoff_request is performed.
This leads to disabling the dev mode in TPM, but the battery is
subsequently cut off so the nvmem contents never stick. Therefore,
whenever antirollback_write_space_firmware() is called we know there
was a change in secdata so request cr50 to immediately enable nvmem
commits going forward. This allows state changes to happen immediately.

The fallout from this is that when secdata is changed that current
boot will take longer because every transaction that writes to TPM
nvmem space will perform a write synchronously. All subsequent boots
do not have that effect.

It should also be noted that this approach to the implementation is
a pretty severe layering violation. However, the current TPM APIs
don't lend themselves well to extending commands or re-using code
outside of the current routines which inherently assume all knowledge
of every command (in conflict with vendor commands since those are
vendor-specific by definition).

Aaron Durbin f56c7787ba google/chromeos: disable platform hierarchy on resume for TPM2
On Chrome OS devices that use TPM2 parts the platform hierarchy
is disabled by the boot loader, depthcharge. Since the bootloader
isn't involved in resuming a suspended machine there's no equivalent
action in coreboot to disable the platform hierarchy. Therefore, to
ensure consistent state in resume the platform hierarchy in the TPM2
needs to be disabled as well. For systems that resume using the
firmware the platform hierarchy is disabled when utilizing
TPM2 devices.

BUG=chrome-os-partner:61097
BRANCH=reef
TEST=Suspend and resume. Confirmed 'stop trunksd; tpmc getvf; start
trunksd' shows that phEnable is 0.

Aaron Durbin 16bd2676ce bootstate: add arch specific hook at coreboot exit
The bootstate machine allows one to schedule work at the
boundaries of each state. However, there are no priorities by
design. As such if there are things that need to be performed
that are interdependent between callbacks there's no way to
do that aside from explicitly putting the call in one of the
callbacks.

This situation arises around BS_OS_RESUME, BS_PAYLOAD_LOAD,
and BS_PAYLOAD_BOOT as those are the states where coreboot is
about to exit. As such, provide an architecture specific hook
at these key places so that one is guaranteed any work done
in arch_bootstate_coreboot_exit() is after all callbacks in
the state machine.

Vadim Bendebury 289ee8f0e9 lib/tpm2: do not create all NVRAM spaces with the same set of attributes
The TPM spaces created by the RO need to have different attributes
depending on the space's use. The firmware rollback counter and MRC
hash spaces are created by the RO code and need to be protected at the
highest level: it should be impossible to delete or modify the space
once the RO exits, and it is how it is done before this patch.

The rest of the spaces should be possible to modify or recreate even
after the RO exits. Let's use different set of NVRAM space attributes
to achieve that, and set the 'pcr0 unchanged' policy only for the
firmware counter and MRC cache spaces.

The definitions of the attributes can be found in "Trusted Platform
Module Library Part 2: Structures", Revision 01.16, section "13.2
TPMA_NV (NV Index Attributes)."
