  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
  86           asm/cdmm.h).

 120           An example of such a bus controller is the Renesas Bus State
 121           Controller (BSC, sometimes called "LBSC within Bus Bridge", or

 136 # the driver will fail to build as a module. However there are patches to
