commit 501c8d83776bf60c395dfa7864bbc5efc53896e3 Author: Hung-Te Lin hungte@chromium.org Date: Tue Jan 29 02:15:49 2013 +0800
cbfstool: Use cbfs_image API for "print" command.
First attempt to process CBFS ROM image by cbfs_image API. To verify, run "cbfstool coreboot.rom print -v" and compare with old cbfstool.
