SGI O2 Port

[Keith M Wesolowski <wesolows@foobazco.org>]

Hi,

I'd like to encourage anyone interested in an SGI O2 port to try my
current CVS tree.  I have successfully reached userland with this
tree.  If you have an O2, please try this and let me know how it goes,
then send patches for all the broken stuff.

Note: This is a 64-bit port.  You will need a mips64 toolchain to
compile.

Known problems:

- Without CONFIG_UNCACHED, the PCI devices don't work properly
- Userland console I/O is very slow and seems unreliable
- Onboard ethernet isn't yet supported; you'll need a PCI one
- Serial console only at this time
- The disks probably work, but I haven't really tested them

Sources: :pserver:cvs@cvs.foobazco.org:/g/cvs mod linux pass cvs

Thanks: 

- Harald Koerfgen, for starting the 32-bit port.  Some of his code
still remains.

- Nick Brisebois, for the loan of an O2, assistance with
documentation, and lots of other stuff.

- The usual suspects, for providing the basis for all this.
