I'm confused - how did a private email to Martin end up in some Cirrus related
mailing list?

Arm doesn't have something called OpenFirmware, still new config  
entries that refer to that name are added. Why no keep _one_ name for  
what you add? I find the random mix of "OF" and "Device Tree" rather  
confusing.

Is the ICE similar to this? :

drivers/mtd/maps/integrator-flash.c: In function 'armflash_probe':
drivers/mtd/maps/integrator-flash.c:262: internal compiler error: in remove_insn, at emit-rtl.c:3803
Please submit a full bug report,
with preprocessed source if appropriate.

If so, I reported that to the compiler guys in ARM and I think it
got fixed in the 2010q3 codesourcery toolchain (not sure where it
is upstream).
