From: Alan Chiang <alanx.chiang@xxxxxxxxx> Currently the only way to use a variant of a supported model with a different address with a different address width is to define a new compatible string and the corresponding chip data structure. Provide a flexible way to specify the size of the address pointer by defining a new property: address-width.
