[U-Boot-Users] Port for Cirrus Logic EDB9312 revision 2

[llandre]

I have a first working port on the Cirrus Logic EDB9312 board, revision 2.
I merged the code released by Adam Bezanson. Linux 2.6.8-rc3-ep93xx boots fine.
As I did not change the default BootROM clock settings the performances
are still terrible (see BogoMIPS below).
As root file system I used the NFS provided by Denx Embedded Linux Kit 
2.1.0 (www.denx.de).


bash-2.05# cat /proc/version
Linux version 2.6.8-rc3-ep93xx (llandre at LinuxServer) (gcc version 3.3.2) #2

To do:
1) adjust clock settings and cache enabling in U-Boot
2) update the build system according to the new rules (waiting a response 
from Wolfgang)
3) fix an ethernet problem I encountered with 100 MBps switch.

If anybody is interested, I can make a preliminary patch available.
