Author: mcayland Date: Sat Jul 3 16:39:49 2010 New Revision: 809 URL: http://tracker.coreboot.org/trac/openbios/changeset/809
Log: Move the separate ISO9660 handler into a new /packages/iso9660-files package in preparation for some future work. Based heavily on Laurent's original patch posted to the list.
