Add support for the IEI JUKI-511P and IEI ROCKY-512 half-size boards.

Both are very similar, thus both use the JUKI-511P target.

Linux with patches from Juergen Beisert
(http://www.linuxbios.org/pipermail/linuxbios/2007-May/020932.html)
boots and work fine (ide, usb, ethernet, serial, keyboard and sound
work normally).

Problems:
 - Filo loads a bzImage only from ide0 (ide1 doesn't work yet).
 - Video doesn't work, yet.
