          The WEIM(Wireless External Interface Module) works like a bus.
          You can attach many different devices on it, such as NOR, onenand.

+         Driver needed for the MIPS Common Device Memory Map bus in MIPS
+         cores. This bus is for per-CPU tightly coupled devices such as the
+         Fast Debug Channel (FDC).

+         For this to work, either your bootloader needs to enable the CDMM
+         region at an unused physical address on the boot CPU, or else your
+         platform code needs to implement mips_cdmm_phys_base() (see
+         asm/cdmm.h).
