This flash is regular CFI compatible (Intel or AMD extended) flash chips with
|
|
some special bits that can be controlled by the machine's system controller.
|
|
|
|
Required properties:
|
|
- compatible : must be "cortina,gemini-flash", "cfi-flash";
|
|
- reg : memory address for the flash chip
|
|
- syscon : must be a phandle to the system controller
|
|
- 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@30000000 {
|
|
compatible = "cortina,gemini-flash", "cfi-flash";
|
|
reg = <0x30000000 0x01000000>;
|
|
syscon = <&syscon>;
|
|
bank-width = <2>;
|
|
};
