makeuimage

# makeuimage [<output-directory> [<make-args>]]
#	Builds armhf kernel and puts output in the subdirectory output/<output-directory>.
#	If <output-directory> isn't specified, it's set to "sun4i_default".
#	If <make-args> is specified, these are passed to make; otherwise, the kernel and modules
#	are built and then installed in output/<output-directory>/output/boot and 
#	output/<output-directory>/output/lib.  If output/<output-directory> is being created for
#	the first time and no configuration has been set, sun4i_defconfig is used.
#	
#	Examples:
#		makeuimage 3.4.61-sun7i+ sun7i_defconfig	# first time setup of output/3.4.61-sun7i+
#		makeuimage 3.4.61-sun7i+ menuconfig			# run menuconfig on output/3.4.61-sun7i+
#		makeuimage 3.4.61-sun7i+ 					# build kernel and modules
