Connection between flash and controller is not necessary to be always of same type. It may varies from platform to platform. Adding endianness (optional) property to provide connection type information. This endianness property is checked in physmap_of_core.c to decide swap type. This patch also set "big-endian" property for ls1021a, ls1043a and ls1046a device tree. here connection between IFC controller and NOR flash is big-endian.
