Hi Yousong, the main issue on ar71xx is the high number of mach-*.c files for all the boards being included in *all* images. Once the target has been migrated to device tree (which is a huge amount of work, lynxis has done major progress there), this should easily free 500 kB of the uncompressed kernel image.
