possible other causes:
* no clock to the respective UART (see untested patch below)
* baud rate configuration issue (unlikely if serial console works)
* some flow control related problem

As Andy pointed out, it is just an ext2 partition. If u-boot is compiled
with ext2 support, you should be able to use the standard ext2ls and ext2load
commands of u-boot.
Looking forward to meeting you later today ;)
