AMB - AXI MBUS address decoding =============================== AXI to M-bridge decoding unit driver for Marvell Armada 8K and 8K+ SoCs. The Runit offers a second level of address windows lookup. It is used to map transaction towards the CD BootROM, SPI0, SPI1 and Device bus (NOR). The Runit contains eight configurable windows. Each window defines a contiguous, address space and the properties associated with that address space. :: Unit Bank ATTR Device-Bus DEV_BOOT_CS 0x2F DEV_CS0 0x3E DEV_CS1 0x3D DEV_CS2 0x3B DEV_CS3 0x37 SPI-0 SPI_A_CS0 0x1E SPI_A_CS1 0x5E SPI_A_CS2 0x9E SPI_A_CS3 0xDE SPI_A_CS4 0x1F SPI_A_CS5 0x5F SPI_A_CS6 0x9F SPI_A_CS7 0xDF SPI SPI_B_CS0 0x1A SPI_B_CS1 0x5A SPI_B_CS2 0x9A SPI_B_CS3 0xDA BOOT_ROM BOOT_ROM 0x1D UART UART 0x01 Mandatory functions ------------------- - marvell_get_amb_memory_map Returns the AMB windows configuration and the number of windows Mandatory structures -------------------- - amb_memory_map Array that include the configuration of the windows. Every window/entry is a struct which has 2 parameters: - Base address of the window - Attribute of the window Examples -------- .. code:: c struct addr_map_win amb_memory_map[] = { {0xf900, AMB_DEV_CS0_ID}, };
