[LinuxBIOS] [PATCH] Intel 82371EB: IDE init support (or: S1846 boots Linux kernel)

Here's a patch which adds IDE support to the Intel 82371EB southbridge.

With this patch I can boot a Linux kernel with FILO up until the login
prompt. I can login and use the system, too. Feels a bit slowish, but
maybe that's just because the CPU and disk are dead slow...

(Hm, there's an "Enable Ultra DMA/33" setting on the IDE controller --
should I enable that in the southbridge code, or can Linux do that and
it's superfluous in the BIOS?)

Anyway, this patch also fixes random other southbridge files, and I'm
adding my copyright header to some other files as they're either
trivial and/or my changes are pretty much a rewrite...

There's some more stuff missing from the 82371EB (e.g. USB support),
but that's for another patch...

Boot log attached.


Uwe.
