commit 70087e81a3c1ada22bcc65bbb0f1e9d135e0590e Author: Gerd Hoffmann kraxel@redhat.com Date: Tue Jun 18 23:41:21 2013 +0200
qemu: complete bochs dispi interface vga driver.
Ditch unused fb*.h files. Rename init.c (name is _way_ to generic) to bochs.c. Add proper bochs dispi interface detection and mode setup. Hook up coreboot framebuffer table initialization.
