sbtools: add brute force option for sb1 in sbtoelf

2013-02-16T19:49:07+00:00

After some reverse engineering, it appears that the keys of the
sb1 format are very weak: the 128 bytes are generated from the
laserfuse words 4,5 and 6 but in a weird manner: 4 and 5 are
simply ORed and 6 is only half used (somehow), making it "only" a
48 bit word to find.

sbtools: add support for the stmp36xx format

2012-11-26T22:58:30+00:00

The STMP36xx series also uses .sb files but with a different
format. The main differences are the encryption and the lack of
sections, making it basically a list of commands: fill, load,
call, jump, switch mode, set sdram settings. Currently only the
sbtoelf has support for the sb1 and can only dump the list of
commands. Actual support for elf creation will come later.
