 81           Fast Debug Channel (FDC).
 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
