At this point, this seem to be a copy of da830evm.c (well except the first few lines above).

Copied code is not good. I have changes still in the pipe line for da830evm.c for adding
support for NAND and Ethernet and there is a USB patch out there IIRC.

Since the da850 is so similar, I suspect we can at least factor out the common parts so
that we don't have to edit two files to add NAND support for example.

I think it is the case that the only difference is DDR instead of SDRAM and the UBL will
handle that for us. Is that true for the device *and* the EVM? If so, then possibly
da830evm.c could be renamed to da8xxevm.c and the code kept completely common - at the risk
of adding a few ifdefs later.

Nick.
