Not sure what was wrong. We took a step back, and redid some stuff, and
now we have serial output from the boot-wrapper.
THe checkstop came from the wrapper grying to access the bcsr and doing
the chip select fixup. We don';t have a bcsr on our board, and the cs
layout is different.

Now our problem is that the kernel doesn't want to output anything to
hte serial port.
