mn10300: add the MN10300/AM33 architecture to the kernel Add architecture support for the MN10300/AM33 CPUs produced by MEI to the kernel. This patch also adds board support for the ASB2303 with the ASB2308 daughter board, and the ASB2305. The only processor supported is the MN103E010, which is an AM33v2 core plus on-chip devices.

kernel: Move arches to use common unaligned access Unaligned access is ok for the following arches: cris, m68k, mn10300, powerpc, s390, x86 Arches that use the memmove implementation for native endian, and the byteshifting for the opposite endianness. h8300, m32r, xtensa Packed struct for native endian, byteshifting for other endian: alpha, blackfin, ia64, parisc, sparc, sparc64, mips, sh m86knommu is generic_be for Coldfire, otherwise unaligned access is ok. frv, arm chooses endianness based on compiler settings, uses the byteshifting versions. Remove the unaligned trap handler from frv as it is now unused. v850 is le, uses the byteshifting versions for both be and le. Remove the now unused asm-generic implementation.
