Update:
The PR now uses a series of reverts, and the reapplies the needed patches.

* It can be discussed if the changes introduced above should instead be applied as edits on the original commits, in order to reduce the size of the patch set to carry around.

In order to keep the 'west ncs-loot' output accurate and thus the next rebase clean, it would be better to see a revert + reapply style patch series. But if that is too complex, we can defer for now and clean up a bit during the rebase.

By the way, the revert+reapply rules are basically just a way to maintain a quilt patch stack in git.

Will do that.
Not difficult at all, I was just wondering what strategy you preferred.
And now that I know, I will follow that principle ;-)

@mbolivar had to revert a series of patches to get down to the [nrf noup] 0fa1f04 without to avoid a lot of merge conflicts and keeping history nice.
Then I reapplied all needed patches again.

Let me know if this has been done in desired way.

Let me know if this has been done in desired way.

I had to hack up zephyr/west.yml a bit to use ncs-loot with it since mcuboot is not in the upstream manifest yet, but with that done, here is the resulting list of OOT patches:
