mkimage.wrapper

这个linux源代码是很全面的~基本完整了~使用c编译的~由于时间问题我没有亲自测试~但就算用来做参考资料也是非常好的

#!/bin/bash

#
# Build PPCBoot image when `mkimage' tool is available.
#

MKIMAGE=$(type -path mkimage)

if [ -z "${MKIMAGE}" ]; then
	# Doesn't exist
	echo '"mkimage" command not found - PPCBoot images will not be built' >&2
	exit 0;
fi

# Call "mkimage" to create PPCBoot image
${MKIMAGE} "$@"
