Driver for i.MX WEIM controller.
The WEIM(Wireless External Interface Module) works like a bus.
You can attach many different devices on it, such as NOR, onenand.
config [31mCONFIG_MIPS_CDMM[0m
bool "MIPS Common Device Memory Map (CDMM) Driver"
depends on [31mCONFIG_CPU_MIPSR2[0m
help
Driver needed for the [31mCONFIG_MIPS[0m Common Device Memory Map bus in [31mCONFIG_MIPS[0m
cores. This bus is for per-CPU tightly coupled devices such as the
Fast Debug Channel (FDC).
For this to work, either your bootloader needs to enable the CDMM
region at an unused physical address on the boot CPU, or else your
platform code needs to implement mips_cdmm_phys_base() (see
asm/cdmm.h).

help
Driver for transparent busses that don't need a real driver, but
where the bus controller is part of a [31mCONFIG_PM[0m domain, or under the control
of a functional clock, and thus relies on runtime [31mCONFIG_PM[0m for managing
this [31mCONFIG_PM[0m domain and/or clock.
An example of such a bus controller is the Renesas Bus State
Controller (BSC, sometimes called "LBSC within Bus Bridge", or
"External Bus Interface") as found on several Renesas [31mCONFIG_ARM[0m SoCs.
