+applies to the 85xx CDS boards as well. In particular the toolchain,
the switch nomenclature, and the basis for the memory map. There are
some differences, though.
The mapping is:

The boot bank is always mapped to FF80_0000 and listed first by
the "flinfo" command. The secondary bank is always FF00_0000.
