  82
  83           For this to work, either your bootloader needs to enable the CDMM
  84           region at an unused physical address on the boot CPU, or else your
  85           platform code needs to implement mips_cdmm_phys_base() (see

 128           this PM domain and/or clock.
 129           An example of such a bus controller is the Renesas Bus State
 130           Controller (BSC, sometimes called "LBSC within Bus Bridge", or
