IO requests are routed to this bus by means of the DW AMBA 3 AXI Interconnect. In case of any APB protocol collisions, slave device not responding on timeout an IRQ is raised with an erroneous address reported to the APB terminator (APB Errors Handler Block). This driver provides the interrupt handler to detect the erroneous address, prints an error message about the address fault, updates an errors counter. The counter and the APB-bus operations timeout can be accessed via corresponding sysfs nodes. config BT1_AXI bool "Baikal-T1 AXI-bus driver" depends on MIPS_BAIKAL_T1 || COMPILE_TEST select MFD_SYSCON help AXI3-bus is the main communication bus connecting all high-speed peripheral IP-cores with RAM controller and with MIPS P5600 cores on Baikal-T1 SoC. Traffic arbitration is done by means of DW AMBA 3 AXI Interconnect (so called AXI Main Interconnect) routing IO requests from one SoC block to another. This driver provides a way to detect any bus protocol errors and device not responding situations by means of an embedded on top of the interconnect errors handler block (EHB). AXI Interconnect QoS arbitration tuning is currently unsupported. 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.

The driver is needed to set up various chip select configuration parameters before devices on the expansion bus can be discovered. config MIPS_CDMM bool "MIPS Common Device Memory Map (CDMM) Driver" depends on CPU_MIPSR2 || CPU_MIPSR5 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 tristate "OMAP INTERCONNECT DRIVER" depends on ARCH_OMAP2PLUS 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.
