This is incorrect. Your description of the minor numbers and the meaning
of the device is right, but you're using entirely bogus names. They
should be mtd0, mtd0ro, mtd1, mtd1r0, etc. The device node with major
90, minor 10 is supposed to be called '/dev/mtd5'. If you use MAKEDEV or
udev, or if you just bother to follow the documentation, this should be
correct.

Do not top-post.
