Author: mcayland Date: Fri Apr 2 15:29:12 2010 New Revision: 727 URL: http://tracker.coreboot.org/trac/openbios/changeset/727
Log: Since the original boot code had been previously refactored to make use of saved-program-state, we can take the existing code and with only slight modification use it as a C implementation of the go word.
