This patch adds support for the new CONFIG_CBFS_VERIFICATION feature to cbfstool. When CBFS verification is enabled, cbfstool must automatically add a hash attribute to every CBFS file it adds (with a handful of exceptions like bootblock and "header" pseudofiles that are never read by coreboot code itself). It must also automatically update the metadata hash that is embedded in the bootblock code. It will automatically find the metadata hash by scanning the bootblock for its magic number and use its presence to auto-detect whether CBFS verification is enabled for an image (and which hash algorithm to use).
