U-Boot custodian workflow

[Remy Bohmer]

Hi,

Regarding the Custodian workflow I have a general question: why do we
follow a rebase flow for the custodian trees? If custodians merge master
frequently into their own branches and merge that back on pull requests
would technically work too right?
But there are downsides to it why this is not done like that. Can you give
me a summary of the issues to be faced here?

Kind regards,

Remy
