GBIOS release

[Adrian Cox]

Our in-house PowerPC boot code is now released under GPL, and can be
found at http://www.agelectronics.co.uk/gbios/

It's main trick is PCI configuration, which we've tested with fairly
large "christmas tree" configurations using PCI bridge evaluation
boards.

It can load a kernel using bootp and tftp. It also has some hooks for
running on PCI agents, and some simple memory test code included. So far
it runs on our own TPE4 board, and on the Sandpoint with a MPC107
"Altimus" PMC.
