No you don't. All you need to do is provide something based on the
physmap.c file which the CFI chip driver can use to access the chips. In
fact, in the majority of cases you should get away with only changing a
couple of #defines in that file to say where in physical memory the chips
are, and how large the range is that they're mapped into.
