Matt DeVillier 9bb805e0c9 util/chromeos/crosfirmware: Improve matching when scanning manifest file 
To ensure we find the correct firmware image, match against `$BOARD":`
rather than just `$BOARD`. This fixes an issue where another board (b1)
using the same firmware build or name as the one we are searching for,
causes the grep matching to return empty strings.

TEST=successfully extract the firmware image for CAREENA, which
previously failed.

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
