Matt DeVillier cfe1e921dd util/crosfirmware: Add support for parsing from manifest.json
Some ChromeOS recovery images, such as for GRUNT, support multiple
boards / multiple bios/ec images, but do not break them out in a
'models' subdirectory like modern recovery images do. Instead,
they use a manifest.json to map the board name to the correct
bios/ec images. Add support for parsing out the info from here.

TEST=run `util/chromeos/crosfirmware.sh kasumi` and verify
that the correct shellball firmware is extracted from the recovery
image.

ChromeOS Scripts

These scripts can be used to access or generate ChromeOS resources, for example to extract System Agent reference code and other blobs (e.g. mrc.bin, refcode, VGA option roms) from a ChromeOS recovery image.

crosfirmware.sh

crosfirmware.sh downloads a ChromeOS recovery image from the recovery image server, unpacks it, extracts the firmware update shell archive, extracts the firmware images from the shell archive.

To download all ChromeOS firmware images, run

$ ./crosfirmware.sh

To download, e.g. the Panther firmware image, run

$ ./crosfirmware.sh panther

extract_blobs.sh

extract_blobs.sh extracts the blobs from a ChromeOS firmware image.

Right now it will produce the ME firmware blob, IFD, VGA option rom, and mrc.bin.

gen_test_hwid.sh

gen_test_hwid.sh generates a test-only identifier in ChromeOS HWID v2 compatible format.

Usage:

$ ./gen_test_hwid.sh BOARD_NAME

Example:

$ ./gen_test_hwid.sh Kukui
KUKUI TEST 9847
