  	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.

  config MOXTET
  	tristate "CZ.NIC Turris Mox module configuration bus"
  	depends on SPI_MASTER && OF
  	help
  	  Say yes here to add support for the module configuration bus found
  	  on CZ.NIC's Turris Mox. This is needed for the ability to discover
  	  the order in which the modules are connected and to get/set some of
  	  their settings. For example the GPIOs on Mox SFP module are
  	  configured through this bus.

  config HISILICON_LPC

  config IMX_WEIM
  	bool "Freescale EIM DRIVER"
  	depends on ARCH_MXC
  	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 PLAT_ORION
  	help
  	  Driver needed for the MBus configuration on Marvell EBU SoCs
  	  (Kirkwood, Dove, Orion5x, MV78XX0 and Armada 370/XP).

  config OMAP_INTERCONNECT

  	help
  	  Driver to enable OMAP interconnect error handling driver.

  config OMAP_OCP2SCP
  	tristate "OMAP OCP2SCP DRIVER"
  	depends on ARCH_OMAP2PLUS

  	help

  	  Driver to enable ocp2scp module which transforms ocp interface
  	  protocol to scp protocol. In OMAP4, USB PHY is connected via
  	  OCP2SCP and in OMAP5, both USB PHY and SATA PHY is connected via
  	  OCP2SCP.

  config QCOM_EBI2

  	  Say y here to enable support for the Qualcomm External Bus
  	  Interface 2, which can be used to connect things like NAND Flash,
  	  SRAM, ethernet adapters, FPGAs and LCD displays.

  config SIMPLE_PM_BUS

  	tristate "Simple Power-Managed Bus Driver"

  	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.

  config SUN50I_DE2_BUS

  	  default ARM64
  	  depends on ARCH_SUNXI
  	  select SUNXI_SRAM
  	  help
  	  Say y here to enable support for Allwinner A64 DE2 bus driver. It's
  	  mostly transparent, but a SRAM region needs to be claimed in the SRAM
  	  controller to make the all blocks in the DE2 part accessible.

  config SUNXI_RSB
