+          Some platforms place the NAND chip size in a scratch register
+          because (some versions of) the driver aren't able to automatically
+          determine the size of certain chips. Set the address of the
+          scratch register here to enable this feature. On Intel Moorestown
+          boards, the scratch register is at 0xFF108018.
