I could test on the MX95 if we can somehow ... figure this out. Then I 
can provide RB/TB easily. I don't have MX8qxp device.

SCU is only a register accessor, PRG is another block in the DC, I think

multiple reusable blocks, so we can compose them for both MX8qxp and 
MX95 the right way and reuse most of the code, right ?
