0045 help
0046 Baikal-T1 AXI-APB bridge is used to access the SoC subsystem CSRs.
0047 IO requests are routed to this bus by means of the DW AMBA 3 AXI
0048 Interconnect. In case of any APB protocol collisions, slave device
0049 not responding on timeout an IRQ is raised with an erroneous address
0050 reported to the APB terminator (APB Errors Handler Block). This
0051 driver provides the interrupt handler to detect the erroneous
0052 address, prints an error message about the address fault, updates an
0053 errors counter. The counter and the APB-bus operations timeout can be
0054 accessed via corresponding sysfs nodes.

0061 AXI3-bus is the main communication bus connecting all high-speed
0062 peripheral IP-cores with RAM controller and with MIPS P5600 cores on
0063 Baikal-T1 SoC. Traffic arbitration is done by means of DW AMBA 3 AXI
0064 Interconnect (so called AXI Main Interconnect) routing IO requests
0065 from one SoC block to another. This driver provides a way to detect
0066 any bus protocol errors and device not responding situations by
0067 means of an embedded on top of the interconnect errors handler
0068 block (EHB). AXI Interconnect QoS arbitration tuning is currently
0069 unsupported.

0117 For this to work, either your bootloader needs to enable the CDMM
0118 region at an unused physical address on the boot CPU, or else your
0119 platform code needs to implement mips_cdmm_phys_base() (see
