Also add a script for splitting a firmware image into component firmware data, vblocks and the GBB. Note: The script uses fmap_decode, a utility to parse flashmap of a firmware image, and a part of the flashmap project: http://code.google.com/p/flashmap/ BUG=3496 TEST=Tested with newer builds of firmware images with flashmaps enabled. Steps to verify: 1) Use script to re-sign an existing image with a new set of keys. 2) Use unpack_firmwarefd.sh to get individual firmware data and vblocks. 3) Use vbutil_firmware with the new keys. Verification should succeed with the newer keys but fail with the older ones. Review URL: http://codereview.chromium.org/3026018
lib/ is stuff that the BIOS needs to link with. stub/ is stuff to be implemented by the BIOS. include/ describes the interfaces between the two parts.
