The EBI (External Bus Interface) is used to access external peripherals (NOR, SRAM, NAND, and other specific devices like ethernet controllers). Each device is assigned a CS line and an address range and can have its own configuration (timings, access mode, bus width, ...). This driver provides a generic DT binding to configure a device according to its requirements. For specific device controllers (like the NAND one) the SMC timings should be configured by the controller driver through the matrix and smc syscon regmaps.
