mtd: add DT bindings for the Intel IXP4xx Flash (8b3cc926) · Commits · 戴 / test

This adds device tree bindings for the Intel IXP4xx flash controller, a simple physmap which however need a specific big-endian or mixed-endian access pattern to the memory. Cc: devicetree@vger.kernel.org Reviewed-by:

		Flash device on Intel IXP4xx SoC

		This flash is regular CFI compatible (Intel or AMD extended) flash chips with
		specific big-endian or mixed-endian memory access pattern.

		Required properties:
		- compatible : must be "intel,ixp4xx-flash", "cfi-flash";
		- reg : memory address for the flash chip
		- bank-width : width in bytes of flash interface, should be <2>

		For the rest of the properties, see mtd-physmap.txt.

		The device tree may optionally contain sub-nodes describing partitions of the
		address space. See partition.txt for more detail.

		Example:

		flash@50000000 {
		compatible = "intel,ixp4xx-flash", "cfi-flash";
		reg = <0x50000000 0x01000000>;
		bank-width = <2>;
		};
