btw, please listen to henrik: he knows what he's talking about, as you can see :) henrik, thank you for correcting my technical misunderstandings, i'll try to remember them and not propagate incorrect stuff.

i am - honest! yes it's a little past my bed-time, but hey...

henrik, jon (smirl), can i ask you both a favour? could you write something up, preferably short, that i could put forward to allwinner? describing what's needed, who would need to do what and so on.

i still also - really - need a good justification for this. something which helps explain clearly what the immediate or perhaps strategic benefits would be to allwinner, as to why they should accept such changes. i cannot emphasise enough how important that is.
if someone can please help come up with a good justification as to why allwinner should change their working practices, that would be enormously helpful i feel, to solving this issue.
otherwise we are stuck in the current situation which nobody really likes. i'm inviting you - linux kernel developers - i'm giving you an opportunity to *fix* things. you have 2 weeks to come up with a solution, which can be presented in a simple format. that's the window of opportunity.
