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. Dinh
