this is the thing: picking up patches from patchwork is not something
you'd do regularly - this is just my way of populating the review site
from a single test account.

If this workflow were adopted, each user would push their patch to the
gerrit server, creating a new review branch for that particular patch.
In general, gerrit view of the branch matches the submitter's view of
the branch - if the submitter has several patches in one branch, they
will all be uploaded by gerrit to the same separate branch,
maintaining the relationship between the patches.

This is correct, if you decide to use the google infrastructure based
server. But you don't have to, gerrit is a stand alone application
which can be easily installed on the same server or on a different
server in the same location where the master u-boot git server is,
with you (denx.de) having full control over it.

Google hosting has advantages of providing extremely high bandwidth
and reliability, but google's version of gerrit (distributed and
replicated) is not a requirement, as i said, gerrit could be hosted on
a linux machine.

This is odd, can you maybe send me a screenshot of this browser window
with the `settings' link displayed, before and after you click on it?

This is a big question for which there is no good answer. Gerrit will
send submitted patches in emails (limited to a configurable max patch
size), but it will not accept email based reviews. So, this would
involve a change in the way things done, I am just suggesting this as
an alternative for consideration.
