42	bool "Baikal-T1 APB-bus driver"
43	depends on MIPS_BAIKAL_T1 || COMPILE_TEST
44	select REGMAP_MMIO
45	help
46	  Baikal-T1 AXI-APB bridge is used to access the SoC subsystem CSRs.
47	  IO requests are routed to this bus by means of the DW AMBA 3 AXI
48	  Interconnect. In case of any APB protocol collisions, slave device
49	  not responding on timeout an IRQ is raised with an erroneous address
50	  reported to the APB terminator (APB Errors Handler Block). This
51	  driver provides the interrupt handler to detect the erroneous
52	  address, prints an error message about the address fault, updates an
53	  errors counter. The counter and the APB-bus operations timeout can be
54	  accessed via corresponding sysfs nodes.

57	bool "Baikal-T1 AXI-bus driver"

61	  AXI3-bus is the main communication bus connecting all high-speed
62	  peripheral IP-cores with RAM controller and with MIPS P5600 cores on
63	  Baikal-T1 SoC. Traffic arbitration is done by means of DW AMBA 3 AXI
64	  Interconnect (so called AXI Main Interconnect) routing IO requests
65	  from one SoC block to another. This driver provides a way to detect
66	  any bus protocol errors and device not responding situations by
67	  means of an embedded on top of the interconnect errors handler
68	  block (EHB). AXI Interconnect QoS arbitration tuning is currently
69	  unsupported.
