Not really, but it's essentially a copy&paste job.

However, you know that the STK500v2 protocol already features a simple
(XOR across all bytes of a packet) checksum, do you?  The JTAG ICE
mkII protocol even has a full CRC implementation.  So if you want, you
could perhaps use that protocol inside your bootloader.
