Hi,

Someone pointed me to this support that is being added in Barebox. I
see that it still has the copyright but does not attribute U-Boot. I'm
just checking if that is that an oversight?

Regards,
Simon

The verified boot implementation looks like it came from U-Boot.

Yes, this is still correct for the recent submissions.

The barebox code only supports the signed configurations with hashed
images, as the goal was to use this for verified boot. Supporting only
this mode keeps the complexity down.

Simon, do you think it is a derived work of the U-Boot FIT code?

Jan Lübbe

I've Cc'ed Jan, who has written the code. Quoting from his first patch
to the barebox mailinglist:
