Caveh Jalali fe95f83fd8 util/chromeos: Add EC header update utility
This adds a new utility for copying ec_commands.h and ec_cmd_api.h from
the chrome EC repo with the appropriate copyright header adjustment.

It is invoked as:

 util/chromeos/update_ec_headers.sh [EC-repo]

where EC-repo is the top of the EC repo from which header files are to
be obtained.

The corresponding files in src/ec/google/chromeec are updated but not
committed. Also, a commit message is suggested with the original git
versions for reference.

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
