Julius Werner would like Patrick Georgi and Aaron Durbin to review this change.
cbfstool: Use cbfs_serialized.h and standard vboot helpers
This patch reduces some code duplication in cbfstool by switching it to
use the CBFS data structure definitions in commonlib rather than its own
private copy. In addition, replace a few custom helpers related to hash
algorithms with the official vboot APIs of the same purpose.
