I don't have any problem with adding XILINX_EDK (or whatever), but
think particular layout is back-assward. Rather than XILINX_EDK
depending on XILINX_VIRTEX/MICROBLAZE, XILINX_VIRTEX/MICROBLAZE should
'select' XILINX_EDK and you need to drop the 'default y' line.
Otherwise the XILINX_EDK option shows up in non-edk config files.

Hmmm, yes. XILINX_DRIVERS is probably better.

Why still have XILINX_EDK? I thought you meant replace XILINX_EDK
with XILINX_DRIVERS.
