The endianness of an architecture is now set up automatically using Kconfig and some common code. The available conversion functions were also expanded to go to or from a particular endianness. Those use the abbreviation le or be for little or big endian. Built for Stumpy and saw coreinfo cbfs support work which uses network byte order. Used the functions which convert to little endian to implement an AHCI driver. The source arch is also little endian, so they were effectively (and successfully) inert.
