3These flash chips are found in the ARM reference designs like Integrator,
4Versatile, RealView, Versatile Express etc.

10Required 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.
