This driver makes it possible to configure the static memory chip selects on the ARM PL172 MultiPort Memory Controller from a set of properties in DT. Configuration of dynamic memory is not supported and is left to the boot loader. The intended usage is to setup timing and configuration for static memory devices like NAND and NOR Flash before they are probed by a driver.
