06bffc6ea5 rm9200 lowevel_init: don't touch reserved/readonly registers
For some reason the AT91rm9200 lowlevel init writes to a bunch of
reserved or read-only addresses.  All the boards seem to define the
value-to-be-written values as zero ... but they shouldn't actually
be writing *anything* there.

No documented erratum justifies these accesses.  It looks like maybe
some pre-release BDI-2000 setup code has been carried along by cargo
cult programming since at least late 2004 (per GIT history).

Here's a patch disabling what seems to be bogosity.  Tested on a
csb337; there were no behavioral changes.

92b50ffef9 cmc_pu2: get mac address from environment
The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.

Also rename load_sernum_ethaddr() to misc_init_r() so we don't need to
handle this board specially in common ARM code.

480ed1dea1 use correct at91rm9200 register name
This fixes a naming bug for at91rm9200 lowlevel init code:
NOR boot flash is on chipselect 0, not chipselect 2.  This
makes code use the register name from chip datasheets.
