Wouldn't it just make it easier for everyone to just execute the diskboot.bin without any kind of encoding or anything?

Surely - you may ask Canon why they protect their intellectual property ;)

i guess thats more security that a wrong firmware do not boot partly, because read out firmware is not encode.

but a better way than encode i think is use on every camera a long word with Camera ID on same address

the firmware can check the id and do nothing then, if wrong
