Jens,
Thanks for the patches. I have acked and committed some of these. Please 
see my comments.

But this would break if AUTOBOOT_DELAY wasn't defined. Don't set 
AUTOBOOT_DELAY to 0 or do a more complete fix.
#if AUTOBOOT_DELAY = 0
   #undef AUTOBOOT_DELAY

I don't think anyone builds this so we wouldn't see it.  We just use 
filo. Can you send the build output?

I think that PNP_IO1 should be 0xfff

{&ops, IT8712F_GPIO, PNP_IO0 | PNP_IO1 | PNP_IO2 | PNP_IRQ0, {0xfff, 0}, 
{0xfff, 0}, {0xff8, 0},},


Please send new patches for the ones that need it.

Thanks,
Marc
