80 cores. This bus is for per-CPU tightly coupled devices such as the
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
86 asm/cdmm.h).

117 where the bus controller is part of a PM domain, or under the control
118 of a functional clock, and thus relies on runtime PM for managing
119 this PM domain and/or clock.
120 An example of such a bus controller is the Renesas Bus State
121 Controller (BSC, sometimes called "LBSC within Bus Bridge", or
122 "External Bus Interface") as found on several Renesas ARM SoCs.
