Which is exactly why having it architecture dependent isn't right... All of these drivers could be needed and used on any OF-based platform. If you have a platform (for instance, a processor connected to an FPGA which has these peripherals in the FPGA) then you should be able to enable these drivers. Just my 2 cents...

I've thought about this more, and I'd really rather not. =A0The lis= t of
affected drivers is short and is not a large maintenance burden. =A0I
