mtd: physmap_of: Add multiple regions and concatenation support
This patch adds support to handle multiple non-identical chips in one
flash device tree node. It also adds concat support to physmap_of. This
makes it possible to support e.g. the Intel P30 48F4400 chips which
internally consists of 2 non-identical NOR chips on one die. Additionally
partitions now can span over multiple chips.
To describe such a chip's, multiple "reg" tuples are now supported in one
flash device tree node. Here an dts example:
flash@f0000000,0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "cfi-flash";
reg = <0 0x00000000 0x02000000
0 0x02000000 0x02000000>;
bank-width = <2>;
partition@0 {
label = "test-part1";
reg = <0 0x04000000>;
};
};
