The SAMA5D3 and SAMA5D2 have different numbers of channels and different channel definitions
Rather than clutter sam_xdmac.h with loads of #if defined (SAMA5D2) stuff would it be better to deal with this in the same way as the memory and pinmap files, etc, and have: _sama5d2x_xdmac.h _sama5d3x_xdmac.h _sama5d4x_xdmac.h Then change sam_xdmac.h to have the more easy to follow #if defined(SAMA5D2) # include "hardware/_sama5d2x_xdmac.h" #elif etc I think that's neater?
