2016-08-27commonlib: cbfs: Add CBFS attribute supportJulius Werner
This patch adds support for the CBFS attributes that were already introduced in cbfstool and libpayload. I'm only copy&pasting the header definitions needed for this once more. Really, we should be unifying the definitions (and possibly part of the code) from cbfstool with commonlib, but apparently that hadn't been done when this feature was introduced and I don't really have time to do it cleanly now. Also add a function to extract info from the compression attribute, which can then be used to run cbfs_load_and_decompress() on the file.

2016-01-06commonlib: Add function to hash contents of a CBFS region.Aaron Durbin
Provide a common routine to hash the contents of a cbfs region. The cbfs region is hashed in the following order: 1. potential cbfs header at offset 0 2. potential cbfs header retlative offset at cbfs size - 4 3. For each file the metadata of the file. 4. For each non-empty file the data of the file. BUG=chrome-os-partner:48412 BUG=chromium:445938 BRANCH=None TEST=Utilized in chromeos cros_bundle_firmware as well as at runtime during vboot verification on glados.

2016-01-06commonlib: Add common cbfs parsing logic to coreboot and cbfstool.Aaron Durbin
To continue sharing more code between the tools and coreboot proper provide cbfs parsing logic in commonlib. A cbfs_for_each_file() function was added to allow one to act on each file found within a cbfs. cbfs_locate() was updated to use that logic. BUG=chrome-os-partner:48412 BUG=chromium:445938 BRANCH=None TEST=Utilized and booted on glados.
