| 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. |

| 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}, |
| }; |
