If we decide to put them under arch/powerpc I'd suggest =
arch/powerpc/platform/83xx/BOARDNAME/

However I'm not sure I think this is a good idea.  We specifically moved =
drivers out of arch/ppc land so they would get proper review via the =
proper subsystem maintainers.  So if its truly unique / simple board =
drivers than the location I suggested is probably fine.  If its =
something that a subsystem exists than I do think it should be down in =
the subsystem driver dir.
