  From what I've seen, the 'syscalls' are not implemented for ARM (hello_world.c
doesn't work for me on the LART either). Look at the *.S file at examples/.
Thus, standalone applications cannot run (or better said - do anything much
useful) as of now.

  When I'm at it, I have trouble with u-boot on the LART - the board hangs
(no response on serial, it is a default build and everything else seems to work
fine) as soon as I try to loads something. I didn't yet begin to track this
down, just in case anyone went into the same problem...
