Hi Benoît,

I agree with you that same code can be used then for i.MX6. There is no
need of a parallel development.

I am thinking about if we need some kind of protection to avoid to
destroy very easy the SOC. Running a fuse command can be much more
dangerous as scrubbing NAND or erasing flash.

What about to add at least a "-y" option when we write the fuses, in the
same way we have for the "nand scrub command" ? This does not forbid to
use the command in scripts, but it can maybe avoid to destroy the SOC
when the command is wrong tipped on the console.

What do you think ?

Best regards,
Stefano Babic
