Nice to see one's work appreciated. A bit of comment below.

There's actually room for one more opcode, so I would recommend implementing 
MASK_WRITE instead of forcing everything to be done in read-modify-write mode.

#define OPCODE_MASKWRITE  3U
#define EMIT_MASKWRITE(addr, val)       OPCODE_MASKWRITE | addr, val

This "constant table" approach could also be implemented for the zynqmp 
platforms, cutting down the size of the SPL considerably.

(Only thing remaining is to have Vivado output these files properly...)
