Yes, there are some sharing. But I think that there will be enough
differences that will ultimately warrant it's own directory. I think
with it's own directory, the Makefile changes stay a bit cleaner. I

One of the biggest differences is that the A10's SDRAM support is going
to be a bit ugly. The main point is that we need to program the FPGA
during U-Boot booting up with a ~>10 MB rbf file while being limited to
the OCRAM's size. I would like to contain this ugliness in it's own
directory.
