So why exactly does A10 have it's own dedicated dir if most of the code is probably shared between A10 and AV/CV ?
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.
Well.. so you'll have to optimize memory consuption of the fpga programming. It may be ugly, but once you are done, you'll want to use the optimized version for everyone -- not to keep two versions.
