Provide support for setting up the framebuffer from EDID
Add three functions to edid.c: void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr) takes an edid and uintptr_t, and fills in a static lb_framebuffer struct as well as setting the static vbe_valid to 1 unless some problem is found in the edid. The intent here is that this could be called from the native graphics setup code on both ARM and x86. int vbe_mode_info_valid(void) returns value of the static vbe_valid. void fill_lb_framebuffer(struct lb_framebuffer *framebuffer) copies the static edid_fb to lb_framebuffer. There is now a common vbe.h in src/include, removed the two special ones. In general, graphics in coreboot is a mess, but graphics is always a mess. We don't have a clean way to try two different ways to turn on a device and use the one that works. One battle at a time. Overall, things are much better. The best part: this code would also work for ARM, which also uses EDID. Change-Id: Id23eb61498b331d44ab064b8fb4cb10f07cff7f3 Signed-off-by: Ronald G.
