Most uClinux setups don't have a dynamic /dev directory.  Instead, you
create all the nodes you want in /dev as part of your vendor Makefile.  So
you will first need to determine the major/minor numbers assigned to the
mmc/sd device by the driver, and then modify your vendor Makefile to create
a corresponding device node.
