10	Required properties:
11	- compatible : must be "arm,versatile-flash", "cfi-flash";
12	- reg : memory address for the flash chip
13	- bank-width : width in bytes of flash interface.
14	
15	For the rest of the properties, see mtd-physmap.txt.
16	
17	The device tree may optionally contain sub-nodes describing partitions of the
18	address space. See partition.txt for more detail.

20	Example:
21	
22	flash@34000000 {
23		compatible = "arm,versatile-flash", "cfi-flash";
24		reg = <0x34000000 0x4000000>;
25		bank-width = <4>;
