Comment 17 for bug 2043448

Hi Loic,

Thanks for the input.
I fixed suggestions in v1.9.
And I also subscribed the nemos-team@LP mailing-list.

Fixed items:
1. Correct SPDX header(GPL-3) in the u-boot-signature.dtsi (for comment#16)
2. Isaac is removed from the maintainer
3. Refine the description of d/control with NemOS information
4. Add a README file to explain the "Providers" and how to generate the development key files

About the packages to change to a single one, as a discussion at yesterday.
We can keep the current design at first, and we should construct a better way to handle the key for boot assets and kernel FIT.
