Split CPU specific configuration from board configuration. CPU, firmware and brick recovery configuration now exist in the config/vendor/${VENDOR_NAME}/${CPU_ID} directory.
Added optional CPU_FLOAT_TYPE which determines the FPU variant of the CPU.
Tweaked some of the file existence logic to be nicer with configure_file targets.
Added GCC_ARM_ prefix to all user-accessible settings. The names of some settings have further change.
Forked development of a generic Eclipse debugging launcher to debug2.launch.in.
