Intentional design by upstream, and then for the actual problem part
(error checking, test suite), Sean is saying he'll fix it, and has
started on it.

Alright, go and update our Kbuild integration to be in sync with current
Linux.  Or just v5.0.  I'd suggest picking up the metadata_csum support
patch but someone did say they'd try and update that (off-list) so that
ext4 filesystem made with default options in the last 5 years (not
exaggerating) work.  I'm not even going to talk about the various level
of out of sync our DTs files are but I do have some hope there will be
more re-syncs especially as it comes to more light that the DT U-Boot
uses can just be the DT the OS gets.  Then tell me it's easy to keep
this stuff in sync.  Because we certainly don't want to just
fork-and-forget again, right?  Because that's why we have both crazy
parse bugs as well as lack of now old-and-expected features.

OK, snark aside, I'm very serious here, any "we'll just import ..."
needs to have a plan to keep it up to date, or be easy enough to do such
that I can set a monthly reminder to check for and do the update.  Every
area where we don't do this is a set of problems waiting to get worse,
as we can see with the hush shell right now as it's one of the oldest
things we stopped syncing with.

Any new cli for U-Boot won't be a default build as a command for a long
while after it's merged.  I'm not sure how much past that point it would
further need to be to become the default cli.  And I'll even repeat what
I said elsewhere about how an sh syntax is a good user feature.  But I
really think we want a shell environment that is not actively adding new
features is a good thing, for the default.  Just how much stuff should
we be doing or need to be doing before we hand things over to the OS?
