(I'm really replying to Tom here not Scott)

As I understand it, the process for getting u-boot/next into
u-boot/master is perhaps:

1) tag u-boot/master for the release
2) merge u-boot/next into u-boot/master (or perhaps you're proposing
rebase u-boot/next onto u-boot/master and then fast-forward merge it).

I think the solution to getting patches into u-boot/master first is
therefore:

1) tag u-boot/master for the release
2) apply, cherry-pick, or merge a branch with just the early commits
into u-boot/master
3) merge u-boot/next into u-boot/master

(hopefully (3) doesn't contain duplicated commits with (2)... the beauty
of the Linux kernel's model is that it wouldn't, and even with U-Boot's
model it wouldn't with sufficient planning)

That way, everything can still be merges, and hence preserve commit IDs,
but we also get any early commits in early.
