	help
	  Baikal-T1 AXI-APB bridge is used to access the SoC subsystem CSRs.
	  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.

	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.

	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).
