Good point...

Yes, that's what I was suggesting.
But I think that Andrei still wants to use XILINX_EDK to pull in the
stuff in drivers/xilinx_common.

# The Xilinx OS common code 
obj-$(CONFIG_XILINX_EDK) += xbasic_types.o xpacket_fifo_l_v2_00_a.o \
			    xpacket_fifo_v2_00_a.o xversion.o \
			    xdma_channel.o xdma_channel_sg.o

Which you wouldn't want if you were able to build a kernel completely
from 'non-edk' drivers.
