     14  AXI3-bus is the main communication bus of Baikal-T1 SoC connecting all
     15  high-speed peripheral IP-cores with RAM controller and with MIPS P5600
     16  cores. Traffic arbitration is done by means of DW AXI Interconnect (so
     17  called AXI Main Interconnect) routing IO requests from one block to
     18  another: from CPU to SoC peripherals and between some SoC peripherals
     19  (mostly between peripheral devices and RAM, but also between DMA and
     20  some peripherals). In case of any protocol error, device not responding
     21  an IRQ is raised and a faulty situation is reported to the AXI EHB
     22  (Errors Handler Block) embedded on top of the DW AXI Interconnect and
     23  accessible by means of the Baikal-T1 System Controller.
