[commit] r1215 - in trunk/openbios-devel: arch/sparc32 arch/x86 drivers forth/device include/drivers include/libopenbios libopenbios
Author: mcayland Date: Mon Aug 19 09:40:33 2013 New Revision: 1215 URL: http://tracker.coreboot.org/trac/openbios/changeset/1215
Log: tcx.fs: move framebuffer mapping over from C to tcx.fs
Finally we can now fix up setup_video() so that it has no knowledge of fixed addresse but simply refers to the underlying Forth variables as per the specification. Touch up various places as a result of this, but we can now remove the bogus openbios-video-addr and just use frame-buffer-adr instead.
