Hi Tom,
Thanks for the excellent review.

I have moved this over to board code instead, since the board should
determine these based on the connected device's timings.

Again, moved these initializations to board code instead. Some boards
may opt to run at different rates.

These are register indices and bit shifts, not really amenable to macro
definition. I have put in a comment for the column contents.
