[commit] r1181 - in trunk/openbios-devel: forth/device include/libopenbios libopenbios packages
Author: mcayland Date: Sat Jul 27 12:14:41 2013 New Revision: 1181 URL: http://tracker.coreboot.org/trac/openbios/changeset/1181
Log: video_common.c: unify the video_info structure with Forth
At the moment there are two sets of video parameters being used: those internal to Forth and those internal to C. Unify these two structures by redefining video_info to contain pointers to relevant values, and then changing init_video() to set the pointers to the relevant values in the Forth dictionary.
