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.
Repeat: should not write to reserved or read-ony addresses.
If there's a real need to write these locations, like an erratum that's not included in the current list, that should be reflected in a source code comment. Looks like maybe some very early BDI-2000 setup code has been carried along by cargo cult programming since at least late 2004 (per GIT history).
Meanwhile, here's a patch/RFC disabling what seems to be bogosity. If it's eventually a "go", the supporting code should be removed.
No comments?
If no comments come for a patch-RFC for some days, you should try and re-post itas a real patch.
Best regards,
Wolfgang Denk
