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

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.

I have found what appears to be a fix. A compiler optimization barrier needs to be inserted after gd (AKA R8) is initialized. See the below snippit.

With out this barrier gd is calculated into a temporary register, and when the gd->bd is actually attempted an unitilized R8 is used causing a fatal abort.

Looks like a compiler bug to me. Anyway. Added. Thanks.
