Trying to compile U-Boot for a Freescale P2020DS target, using the VxWorks GCC PPC Compiler (We don't want to have to maintain another compiler if possible)

After the compile I get the following errors from the linker:

Google searches have not turned up any useful information. It seems that our section sizes are not allocated correctly, but this surprises me as I'd expect the values for a supported board like the P2020DS to be vetted already.

I would suspect insufficient optimization causing the various sections to be too large and thus overlap. Have you ruled that out?
