Since you're getting absolutely no output after uncompression it
probably means that you're failing in the boot wrapper... which means
mmu is off, and the serial port is already set up by u-boot.
You should be able to add direct writes to the uart fifo register from
within the bootwrapper code to see how far you get in the progress.
