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 | |

49 | not responding on timeout an IRQ is raised with an erroneous address | |
50 | reported to the APB terminator (APB Errors Handler Block). This | |

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 | |

68 | block (EHB). AXI Interconnect QoS arbitration tuning is currently | |

106 | For this to work, either your bootloader needs to enable the CDMM | |
