This patch reshapes northbridge and southbridge inclusion. It selects
southbridge drivers in Kconfig. * It includes initial superio code as well, but there is at least one error in the pnp_device.c/superio scenario left * Fixed biosemu.c, vm86.c, pnp_device.c (sort of) * Enable vm86 instead of x86emu per default for vga init for now. This makes VGA in qemu work. There might be a bug in x86emu or the compiler I am using. (gcc version 4.1.2 20070115 (prerelease) (SUSE Linux)) * Import isa-dma.c, keyboard.c and i8259.c from v2 /pc80, which was taken from LinuxBIOSv1 released from LANL under release LA-CC Number 00-34 and using parts from the Linux kernel. This patch makes vga and keyboard work in qemu. Yippie Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Ronald G.
