Author: stepan Date: Mon Feb 22 05:33:13 2010 New Revision: 5135 URL: http://tracker.coreboot.org/trac/coreboot/changeset/5135
Log: YABEL update - drop x86emu + old biosemu in favor of YABEL - Add YABEL_DIRECTHW to get the old biosemu behavior - add support for vesa console using YABEL - add coreboot table entry with console information - add bootsplash support (reads /bootsplash.jpg from CBFS)
