* Add support to get layout from fmap (e.g. coreboot rom)Arthur Heymans2018-10-231-0/+71
Flashmap, or simply fmap, is a binary data format for describing region offsets, sizes, and certain attributes and is widely used by coreboot. This patch adds support for the fmap data format version 1.1 and adds --fmap and --fmap-file arguments. Using --fmap will make flashrom to search the ROM content for fmap data. Using --fmap-file will make flashrom search a supplied file for fmap data. An example of how to update the COREBOOT region of a ROM: flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT The fmap functions are mostly copied from cbfstool. Currently it is made mutually exclusive with other layout options until we are more clever about this input.
