U-Boot now uses errors defined in include/errno.h which are negative integers. Commands which fail need to report the error and return 1 to indicate failure. Add this functionality in cmd_process_error(). For now this merely reports the error number. It would be possible also to produce a helpful error message by storing the error strings in U-Boot.
