The lpc176x internal rom checks that the first 8 words of the flash
sum to zero. Many flash writing tools for the lpc176x will
automatically add the appropriate checksum. However, it can be useful
to build the checksum locally so that the image supports direct flash
writing.

Rename the existing armcm_boot.c file to armcm_canboot.c . This makes
it easier to track changes between CanBoot and Klipper as the CanBoot
entry code is notably different from the Klipper entry code.
