[U-Boot-Users] necessary fix for ARM u-boot 1.1.1 and GCC3.4.0.

[Woodruff, Richard]

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.
