blegh :)

these microwatt functions are awful.  they are heavily optimised for Xilinx
FPGA toolchains (which are s***) to specifically target Xilinx LUT6 FPGAs.

we should not in any way try to replicate or use them.

just replace with shift and mask.

x = addr >> shift
return x[0:16] # but convert to MSB0
