HiThis matches how it was done for pre-K3 TI platforms and it allows us to move the forward declaration out of sys_proto.h. It also removes the need for K3_BOARD_DETECT as one is free to simply override the weak function in their board files as needed.

I use this to perform an fpga based board detection on a am642 platform. That comment goes for every occurance of that line in this patch.
Sure, I'll drop it if this needs a v3, otherwise I can fix in a follow up. Andrew
