I made a few minor changes, but now it looks real good.

Allwinner A20/A31 SoCs have a special interrupt controller for managing NMI.
Three register are present to (un)mask, control and acknowledge NMI.
These two patches add a new irqchip driver in cascade with GIC.

- fixed tr

This may be an issue with the audio/hdmi drivers so could be relevant to
this mailing list. Is anybody using HD video + audio?, I've not plugged my
box into my TV for months so can't really comment on the current status.

I have a few general comments first:
- Use a decent mailer for your patches. git send-email is perfect
for that, use it. Otherwise, your patches will be wrapped, like it
happened here, and they won't be applyable anymore.
- The vX should be between the

Hi Luc,
No problem to document this board.
My user is iso9660, but I cannot see any way I can add a new wiki page when
reading the wiki with my user.
Could be related with my user account's permissions?
