	depends on ARM || ARM64 || MIPS
	default ARCH_BRCMSTB || BMIPS_GENERIC
	help
	  Driver for the Broadcom Set Top Box System-on-a-chip internal bus
	  arbiter. This driver provides timeout and target abort error handling
	  and internal bus master decoding.

	help
	  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).

config MVEBU_MBUS
	bool

	depends on OF && PM
	help
	  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.
