If this "needs to be determined on a board-by-board basis" i would
expect some CONFIG_SYS_* variable here, which is defined in the
respective board config files?

Ditto - this should go to the respective board config files.

Are you sure this is correct?

This looks fishy, too.

Better split code beautifying into separate patch.

You mean you change the mapping for soem (or all) boards?

Hm... did you actually test these changes on all 4 boards?

This is an unrelated change which must be submitted as a separate
