Several recovery images for newer ChromeOS boards fail in extract_partition() due to parted detecting that there are overlapping partitions, and therefore failing to print the partition layout (this is potentially a parted bug; requries further investigation). To work around this, fall back to using fdisk, making the assumption that ROOT-A is always partition #3, and calculate the partition start and size using the sector size. Test: successfully extract coreboot firmware images from recovery images which previously failed to extract (fizz, octopus, volteer).

Chrome OS Scripts
These scripts can be used to access or generate Chrome OS resources, for example
to extract System Agent reference code and other blobs (e.g. mrc.bin, refcode,
VGA option roms) from a Chrome OS recovery image.
crosfirmware.sh
crosfirmware.sh downloads a Chrome OS 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 Chrome OS 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 Chrome OS 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 Chrome OS HWID v2
compatible format.
Usage:
$ ./gen_test_hwid.sh BOARD_NAME
Example:
$ ./gen_test_hwid.sh Kukui
KUKUI TEST 9847
