Microblaze does not support the Linux DMA mapping API at this point, so disable CONFIG_NO_DMA. This lets us use the generic dma-mapping-broken.h implementation instead of providing a different copy. Any drivers that try to use DMA mapping now get omitted from Kconfig or produce a link error, rather than failing silently at run time.

On some architectures there is currently no way for the boot loader

to pass arguments to the kernel. For these architectures, you should

supply some command-line options at build time by entering them

here.
