b035e370a7 vboot2: Fix broken compatiblity check for gbb header 1.1
vboot2 supports only GBB header versions 1.1+.  When the GBB header
was rev'd to 1.2, this broke the compatibility check for 1.1.
However, the test was written in such a way that wasn't detected.  Fix
the check and the test.

6df3e33912 Add hwid digest field to GBB header
This adds a field in the GBB header to store the sha256 digest of
the HWID string, and updates gbb_utility so that it stores the
digest when it modifies the HWID. Because this is a new field,
the GBB_MINOR_VER is incremented.

Since the GBB is in the RO firmware, there should be no side

handle a minor version change without complaint).

3638625d35 futility: Be more accepting of how it's invoked
Now that futility is pretty much working as intended, we don't
have to be quite so picky in the way it's being invoked. Up until
now, it's only worked when invoked as "futility" or as one of the
built-in commands, such as "dump_fmap".

This change removes those restrictions. You can invoke futility
under any name you wish. If it recognizes the name as a built-in
command, great. Otherwise it will require a valid command as the
first arg, just like it always has.

  ./blah/usr/bin/futility dump_fmap -h tests/futility/data/bios_peppy_mp.bin

Before this CL, the wrapper didn't work because the binary was
being invoked as futility.elf, which was rejected. After this CL,
the wrapper works fine.

4184e62633 Use VbExStream APIs to read the kernel partition
This is necessary to support reading the kernel from raw NAND flash,
where the driver may need to skip over bad sectors, and absolute
sector addressing is thus not practical.

The impact is relatively minor.  Vboot only did two reads per kernel
anyway, one for the first 64KB of the partition and a second for the
rest of the kernel data.

Firmware which uses vboot will need to implement the streaming APIs.
Or, as a really easy workaround, just copy the implementation from
firmware/stub/vboot_api_stub_stream.c, which translates from the new
streaming API to the old sector-based disk API.

f1dba02034 futility: rolled back vbutil_kernel change

162f788596 vboot_kernel: Validate GPT header before using
In AllocAndReadGptData() the code was changed to use the GPT header
to determine the LBA of the GPT entries.  This change did not account
for devices that have an invalid header and it can attempt to read
from invalid block addresses on a device.

This commit happened here:
a2d72f7 vboot: cgpt: Refer to partition entries by entries_lba.
https://chromium-review.googlesource.com/213861

The subsequent steps in vboot, LoadKernel->GptInit->GptRepair will
fix a missing header and entries, so it is only necessary for one of
the headers to be valid.

This is commonly the case with a new USB stick that has an image
written to it as only the primary header will be valid in this case.
However it is also true if the primary header has been corrupted and
the secondary header is still valid.

The code has been changed to call CheckHeader() on the primary and
secondary headers before attempting to use the 'entries_lba' field
to read the entries from the device.  AllocAndReadGptData() now only
fails if both headers are invalid.

A number of new unit tests are created to check for these failure
conditions.  In order to support this I had to extend the vboot_kernel
test infrastructure to have a buffer for the mocked disk data instead
of just ignoring reads and writes.  This is because many of the existing
tests assumed they could have an invalid GPT header and still pass.
Now that the header is checked it is necessary for a valid header to
be created before the tests can pass.

BRANCH=samus,auron
TEST=All unit tests pass when running 'make runtests'
In addition real-world testing was done by corrupting the primary
and/or secondary headers of USB stick to ensure that it will
successfully boot if one of the headers is valid.

028f468aff vboot2: Move vb2_verify_fw inside of futility
Update the unit tests which use it to use futility.  No functional
changes to it, just relocation.

Remove the futility test which checks the exact list of supported
commands.  This doesn't have a good way of handling
conditionally-compiled commands, and will be even harder to maintain
as we add more commands in the future.  Presence of sub-commands is
still ensured by the other tests which use them (such as
vb2_firmware_tests.sh)

6f3961507e futility: Add remaining vboot binary utilities
This change adds these formerly external utilities into the futility binary:

  dev_sign_file
  dump_kernel_config
  gbb_utility
  vbutil_firmware
  vbutil_kernel

These target binaries will remain independent of futility, since they are
not directly related to verified boot:

  cgpt
  crossystem
  tpm_init_temp_fix
  tpmc

Also, dumpRSAPublicKey is removed from the target, since it is only used on
the build host to create new keypairs.

This change also add several additional tests.

e778adae83 Change VbExEc functions to take a devidx parameter
This will be used in subsequent CLs to support PD software sync.  For
now, only devidx=0 is used.

This changes the external vboot API, so must be checked in at the same
time as changes to the u-boot and depthcharge implementations.  For
now, those implementations should simply check if devidx=0 and fail if
it's not.

18e03706df Clean up exported Mtd* functions
A lot of functions were added some time ago, nominally to support keeping
the firmware in an MTD device that wasn't formatted with the GPT headers.
That work was never completed, so these functions aren't used anywhere.

We may want to resurrect this work at some future point. Until then, this CL
just moves some of the functions into an "unused" file.
