Ah, I didn't realise it had migrated, great!

flash-kernel still has 4 days to go, I think we should wait for 3.19 to
migrate to testing before uploading any more, so I think we should hold
off on your patch until then if that is OK with you?

The big stumbling block at the moment is finding a u-boot with AHCI
support. I've got a tree I can point people at until that gets sorted

I did consider doing a sweep over the dtb files which the kernel builds
and just adding them all, but then I was thinking it might be best to
fault them in as they are tested, any opinions?

I tested on cubieboard2 this morning and it worked ok
(my /etc/flash-kernel/db entry is identical to the one in your patch).

I'll write something up for the wiki shortly (perhaps this week,
although there is a beer festival in town...). I've got notes for the
fully integrated with flash-kernel case as well as the case where that
isn't present yet (i.e. how to bodge the first boot and manually
configure f-k), which should make it possible for people to get
something working and file a wishlist bug against f-k.

I've got an A20 based MELE of some sort on my desk at work, but it's
been sat there for months and I still haven't bothered to solder the
UART cable together, I wouldn't be on me getting round to it any time
