They did that at the time, but it seems it's not needed anymore:

34e04eedd1cf1be714abb0e5976338cc72ccc05f
  of: select OF_RESERVED_MEM automatically

This commit removed those select OF_RESERVED_MEM lines. Is it needed
specifically for microblaze? I didn't need to do that in order for
reserved-memory entries to work on my platform.

Thanks!
