2010-06-09Fix multiboot compilationAlexander Graf
Commit dd4239d6574ca41c94fc0d0f77ddc728510ffc57 broke multiboot. It replaced the instruction "rep insb (%dx), %es:(%edi)" by the binary output of "addr32 rep insb (%dx), %es:(%di)". Linuxboot calls the respective helper function in a code16 section. So the original instruction was automatically translated to its "addr32" equivalent. For multiboot, we're running in code32 so gcc didn't add the "addr32" which breaks the instruction. This patch splits that helper function in one which uses addr32 and one which does not, so everyone's happy. The good news is that nobody probably cared so far. The bundled multiboot.bin binary was built before the change and is thus correct. Please also put this patch into -stable.

2009-11-21Allow build of linuxboot.S with old assemblersJuergen Lock
In the spirit of ff56954baf9cfab5cbbe18d10b4a09e4a17f39a8, fix the build of linuxboot.S with old as(1) (as found in some BSD base systems) by emitting the bytes of the insn it doesn't like instead. Signed-off-by: Juergen Lock <nox@jelal.kn-bremen.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-11-17Move common option rom code to header fileAlexander Graf
We will have a linux boot option rom soon, so let's take all functionality that might be useful for both to a header file that both roms can include. That way we only have to write fw_cfg access code once. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
