[U-Boot] Uboot port for Cortex M1,M3

Hi All,

I have the u-boot port done for Cortex-M1 controller on https://www.actel.com/products/hardware/devkits_boards/m1proasic3l.aspx which can also be extended to be used for the latest Cortex-M3 controller boards. But this processor only supports thumb and thumb2 instructions. With my working tree of u-boot I have created the folder lib_armv6-m for the thumb2 implementation of lib_arm. Please suggest whether this suits with the u-boot directory naming convention. Also please suggest on introducing new architectures for u-boot.

Regards, Shinose.
