[commit] r1182 - in trunk/openbios-devel: arch/sparc32 arch/x86 config/scripts drivers forth/device include/arch/sparc32 include/libopenbios libopenbios
Author: mcayland Date: Sat Jul 27 12:14:44 2013 New Revision: 1182 URL: http://tracker.coreboot.org/trac/openbios/changeset/1182 Log: video_common.c: split video setup routines into setup_video() Leave per-device work in init_video() for the moment. As part of this commit we fix up switch-arch so that CONFIG_QEMU works for SPARC32 - if we are given the framebuffer information via the QEMU firmware interface we use it. Otherwise fall back to the values of the VGA_DEFAULT_* constants. This commit requires a corresponding patch for QEMU as currently the framebuffer width/height are not passed via the firmware interface for SPARC32.
