Programs in tools/ directory are usually built for the host. But some of them (mkimage, dumpimge, gen_eth_addr, etc.) are useful on the target OS too.Actually, prior to Kbuild, U-Boot could build tools for the target like follows: $ make<target_board>_config $ export CROSS_COMPILE=<cross_gcc_prefix> $ make HOSTCC=${CROSS_COMPILE}gcc HOSTSTRIP=${CROSS_COMPILE}strip tools In Kbuild, we can no longer replace HOSTCC at the command line. In order to get back that feature, this commit adds "cross-tools" target. Usage: Build tools for the host $ make CROSS_COMPILE=<cross_gcc_prefix> tools Build tools for the target $ make CROSS_COMPILE=<cross_gcc_prefix> cross_tools Besides, "make cross_tools" strip tools programs because we generally expect smaller storages on embedded systems.
