Please take a look at "[PATCH] Make Sequoia boot vxWorks" posted on Juli 30.
Problem areas are two different chip selects and different TLB settings,
which collide (u-Boot needs TLB#0 for the boot flash and vxWorks needs
TLB#0 for its exception handling).

I have a custom PPC440EPx work where I have to make vxWorks work on it,
which is a real pain. If you are interested to share insight you may also
contact me directly.
