  64           Fast Debug Channel (FDC).
  65
  66           For this to work, either your bootloader needs to enable the CDMM
  67           region at an unused physical address on the boot CPU, or else your
  68           platform code needs to implement mips_cdmm_phys_base() (see
  69           asm/cdmm.h).

  99           Driver for transparent busses that don't need a real driver, but
 100           where the bus controller is part of a PM domain, or under the control
 101           of a functional clock, and thus relies on runtime PM for managing
 102           this PM domain and/or clock.
 103           An example of such a bus controller is the Renesas Bus State
 104           Controller (BSC, sometimes called "LBSC within Bus Bridge", or
 105           "External Bus Interface") as found on several Renesas ARM SoCs.
