Since the CDMM region is a feature of the MIPS architecture (since around MIPSr2) the first patch adds the necessary definitions and probing to arch/mips. The second patch adds the actual bus driver (see that patch for lots more info). The final patch just enables CDMM to work on Malta. Futher patches will follow soon to add TTY/Console/KGDB support for the EJTAG Fast Debug Channel (FDC) device which is found in the CDMM region.
