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@LinuxServer) (gcc version 3.3.2) #2 Fri Aug 20 10:22:46 CEST 2004 bash-2.05# cat /proc/cpuinfo Processor : ARM920Tid(wb) rev 0 (v4l) BogoMIPS : 7.27 Features : swp half thumb CPU implementer : 0x41 CPU architecture: 4T CPU variant : 0x1 CPU part : 0x920 CPU revision : 0 Cache type : VIVT write-back Cache clean : cp15 c7 ops Cache lockdown : format A Cache format : Harvard I size : 16384 I assoc : 64 I line length : 32 I sets : 8 D size : 16384 D assoc : 64 D line length : 32 D sets : 8

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.
