firmware-utils: kernel image generator for TP-Link RE450
The firmware image that is used in TP-Link RE450 (and some more devices from the RE series) is tplink-safeloader. In the kernel partition, the kernel is compressed in a regular tp-link firmware that is just used for booting. Since it is only used for compressing and booting, only four fields are filled in the header: Vendor, version, kernel load address and kernel entry point. mktplinkfw-kernel is a simpler version of mktpolinkfw that generate such images. It also specifies the hardware id (as it is in the product info section), so when doing a sysupgrade - the existing code will check for hardware compatibility.
