The calling firmware can set ctx->flags VB2_CONTEXT_NVDATA_V2 to tell
vboot that nvdata is a 64-byte record instead of a 16-byte record, or
equivalently, set the VBSD_NVDATA_V2 flag if calling the old vboot1
API.
If calling firmware does not (which is the current coreboot and
depthcharge default), then the 16-byte record is used, and V2 fields
return explicit default values.
Added the fw_max_rollforward V2 field, which defaults to 0xfffffffe on
V1. This will be used by a subsequent CL.
Added unit tests to verify all that.
Added crossystem support, though it will only work with the current
16-byte records until firmware sets the VBSD flag and mosys supports
larger records.
(Note that because coreboot/depthcharge do not yet set the new context
flag, this CL should not change ToT firmware behavior.)

The region API was a way for firmware and kernel verification to get
at various blocks of caller-provided data. In practice, we only used
it internally as a way to get at parts of the GBB. Prune it down to
access only the bits of GBB we still need, from the buffer we already
know we have.
In the long run we should use the same vb2ex_read_resource() API that
vb2 firmware verification does, but that should be done in a follow-up
CL since it'll need to be coordinated with support in depthcharge.

Currently, firmware verification uses entirely vb2 structs, including
vb2_shared_data. This goes through an ugly translation to the old vb1
VbSharedData to pass it to depthcharge. The vboot kernel verification
maintains an equally ugly translation back to the vb2 struct
internally.
Eventually, we want to get rid of all that and use vb2 all the way
down to what crossystem picks up from the OS.
But before we can do that, we need to finish translating kernel
verification code to use the new vb2 structs. This is a step on that
path, using vb2_shared_data equivalents where present and hiding the
old vb1 shared data struct as a member of vb2_shared_data so at least
the vboot functions don't need to pass around cparams to get at it.
This will be followed by more CLs which convert more vboot internals
to use vb2 structs directly, and eventually coreboot/depthcharge CLs
which pass the vb2 structs from firmware verification directly to
kernel verification.

If a platform does verification of memory init then it must be careful
to use the same slot for resume that it booted from. This is
accomplished by adding a context flag to indicate this is an S3 resume
and that vboot should treat it differently than a normal boot.
When this flag is set then the same slot that was booted is read from
VBNV and re-used for the resume path, without adjusting any try flags.
If this slot is B then the related context flag is set.
This will allow the firmware updater to update the other (non-booted)
slot and set flags indicating that on the next boot the updated slot
should be tried, while still allowing suspend/resume to work with the
existing firmware slot.
This assumes that the last tried slot was successfully booted, which
should be a safe assumption since the system was able to boot and then
suspend. It isn't reliable to check last_fw_result for "success"
status because that status is only set some time after boot when
chromeos-setgoodkernel calls chromeos-firmwareupdate --mode=bootok
and so it may still report a status of "trying" on resume depending
on how soon after boot the suspend happened.
It also avoids setting the vboot flag indicating that a slot choice
was made in order to avoid altering the try counter on failure since
this is explicitly not attempting to boot the new slot.

When a TPM goes from the disabled state to the enabled state, it must
reboot after being enabled, before it can be initialized. In vboot1,
TLCL was part of vboot and this was handled internally. In vboot2, the
caller must set a context flag, so that vboot can decide whether to
allow the reboot, or whether to go directly to recovery mode. This
check is necessary to handle the following cases:
1) The device is booting normally, but the TPM needs a reboot. This
should simply reboot, without going to recovery mode.
2) The device is booting in recovery mode, but the TPM needs a reboot.
If this is the first time it asked us, allow the reboot.
3) The TPM asked for a reboot last time, so we did. And it's still
asking. Don't reboot, because that runs the risk that whatever is wrong
won't be fixed next boot either, and we'll get stuck in a reboot loop
that will prevent recovery. Boot into recovery mode.
Add a new NvStorage bit to track whether the TPM requested a reboot on
the previous boot. That's better than what we did in vboot1, where we
used a special recovery request. Vboot1 couldn't track getting stuck in
a reboot loop in normal mode, only in recovery mode. The new code can
catch both.

Ryu will store a hash of the GBB root key in a struct inside its boot
block. Add a vb2_ryu_root_key_hash struct for that.
If 'futility gbb_utility' is used to set the root key, also look for a
root key hash struct and fill it in. No error if not found, because
this needs to work on other platforms where the struct is not present.
This way, we don't need to change the signing scripts.
Added a --roothash option which can be used to check if the root key
hash is found, and if so, whether it's empty, valid, or invalid.

Take any existing image.bin.
cp image.bin image.orig
gbb_utility --roothash image.bin
- ryu root hash not found
Extract the root key
gbb_utility -k rootkey.bin image.bin
- exported root_key to file: rootkey.bin
Now, append a blank ryu root hash struct to it
echo '0000000: 5274 4b79 4861 7368 0100 0000 3000 0000' | xxd -r >> image.bin
echo '0000000: 0000 0000 0000 0000 0000 0000 0000 0000' | xxd -r >> image.bin
echo '0000000: 0000 0000 0000 0000 0000 0000 0000 0000' | xxd -r >> image.bin
Nothing is set yet
gbb_utility --roothash image.bin
- ryu root hash is unset
Setting the root key also sets the root hash
gbb_utility -s -k rootkey.bin image.bin
- import root_key from rootkey.bin: success
- calculate ryu root hash: success
successfully saved new image to: image.bin
See, it verifies
gbb_utility --roothash image.bin
- ryu root hash verified
Now, append a bad ryu root hash struct to it
cp image.orig image.bin
echo '0000000: 5274 4b79 4861 7368 0100 0000 3000 0000' | xxd -r >> image.bin
echo '0000000: 0001 0000 0000 0000 0000 0000 0000 0000' | xxd -r >> image.bin
echo '0000000: 0000 0000 0000 0000 0000 0000 0000 0000' | xxd -r >> image.bin
See, it fails
gbb_utility --roothash image.bin
- ryu root hash does not verify
Make sure the library doesn't contain the magic string
strings `which futility` | grep RtKyHash
(should be no output)

This allows the caller to load the kernel partition and then pass it
to vboot for verification, rather than having vboot assume the kernel
partitions are all on a block storage device.
Next up, APIs for the caller to parse partition information from a GPT
(yes, that's cgptlib, but we'll make it more easily callable by
depthcharge).

This patch reintroduces a vb2_secdata->struct_version check similar to
the one that was removed in CL:244846. The CRC is not a reliable way to
detect zeroed buffers, so this check helps vboot fail earlier and more
clearly in certain situations.

When the lid is closed and external power is applied
the system may boot and shut down faster than required
for the OS to determine that things were alright.
In timed charging setups this led to systems ending up
to consider the current version broken because it "failed"
repeatedly.
Remain generic about the reason for not counting boots
since there may be more situations in which we want to
handle the situation optimistically.

These are slightly more complex than the firmware versions, because
they need to deal with developer-signed keyblocks and keyblock flags.
