Dear Jason Cooper,

The big blocker is that no-one has written  the driver for it. It is
still on our (Free Electrons) TODO-list, but not as a top-priority item
for the moment.

Ok.

Ezequiel had started to do some preliminary cleanup work on the
pxa3xx-nand driver, with the ultimate goal of making it support Armada
370/XP (because the IP in the Armada 370/XP is apparently an evolution
of the PXA3xx NAND controller), but our priorities shifted to those
other topics. We will back on it some day, but I can't say when at the
moment.

Is this under contract?  If so, I don't want to take it from you.  If it
isn't, perhaps Ezequiel and Arnaud could mind-meld?

The big problem is that the Armada 370 and Armada XP datasheets are
still only available under NDA, so it's quite hard for someone to step
up and do this, without access to those datasheets.

bummer.

It used to be on our TODO-list, but isn't any longer, and I have no
informations about when it will re-appear on our TODO-list at this
point.

So, Arnaud, how do you feel about tackling the nand driver based on the
sources you have and the pointers above?

BTW if that can help, I already have a working port of the driver that is
present in Marvell's kernel. The port is absolutely ugly, it's plain copy
paste of the HAL parts that I needed until it built and booted. It worked
on my mirabox with 3.8. I know it doesn't work since recently (I believe
since introduction of the mbus driver) though I haven't had time to check
why yet. The advantage of such an ugly work is that I'm sure that it will
never be merged into mainline :-)

Willy
