Suzuki K. Poulose a95791efa7 arm-cci: Add CCI-500 PMU support
CCI-500 provides 8 event counters which can count any of the
supported events independently. The PMU event id is a 9-bit
value made of two parts.
	bits [8:5] - Source port
			0x0-0x6 Slave Ports
			0x8-0xD Master Ports
			0xf     Global Events to CCI
			0x7,0xe Reserved
	bits [0:4] - Event code (specific to each type of port)

The generic CCI-500 controlling interface remains the same with CCI-400.
However there are some differences in the PMU event counters.
 - No cycle counter
 - Upto 8 counters(4 in CCI-400)
 - Each counter area is 64K(4K in CCI400)
 - The counter0 starts at offset 0x10000 from the base of CCI

Support for PMU events monitoring on the ARM CCI-500 cache coherent
interconnect. CCI-500 provides 8 independent event counters, which
can count events pertaining to the slave/master interfaces as well
as the internal events to the CCI.
If unsure, say Y

PMU (perf) driver supporting the ARM CCN (Cache Coherent Network)
interconnect.

and internal bus master decoding.

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 MIPS_CDMM
bool "MIPS Common Device Memory Map (CDMM) Driver"
depends on CPU_MIPSR2
help
Driver needed for the MIPS Common Device Memory Map bus in MIPS
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).

Driver for transparent busses that don't need a real driver, but
where the bus controller is part of a PM domain, or under the control
of a functional clock, and thus relies on runtime PM for managing
this PM 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 ARM SoCs.
