* rm9200 lowevel_init: don't touch reserved/readonly registersDavid Brownell2009-08-03-5/+0
| | | | | | | | | | | | | | | | | | | 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.

* cmc_pu2: get mac address from environmentMike Frysinger2009-03-20-0/+1
| | | | | | | | | | | | 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.

* use correct at91rm9200 register nameDavid Brownell2008-03-30-1/+1
| | | | | | | | 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
