Yes, I am now able to compile and boot a kernel using 1.1.1 and 3.4.0 after a few changes. I think I've posted the main bits which needed changing (tool chain patch, examples/stubs tweak, lib_arm/board.c optimization stop, as you highlight out per-cpu make file tweak) it looks like it will be ok.

Short-load-bytes is deprecated and needs to be replaced or removed. Per the manual it is only necessary for ARMv3 and below (Ie no half word load available).

Regards,

Richard W.

I just found that lib_arm/board.c:start_armboot()'s GCC3.4.0 generated code sequence breaks ARM u-boot's. I am using the GCC3.4.0 which CodeSourcery put out.

Hmm, that suggests that you have been able to compile it at all? I just tried current CVS with the crosstool-0.28-rc23 gcc and it breaks:
