Hello guys,

this one is targeted to the Free Electrons guys : should I start 
investigating by myself or are you planning to release a patch for 
supporting PCI express on Marvell Armada* platforms ?

Cheers,

Reading the mailing list archives is always a good start:

Look at their github, there is a patchset for the PCI-express. I
managed to get some NICs and the USB3 controller to work in the 
armada370 using it, I have not tried the armadaXP yet.

We have already posted 8 versions of the PCIe patches on this list. The
last version is
http://lists.infradead.org/pipermail/linux-arm-kernel/2013-April/161968.html.
However, this patch set has a few dependencies, so if you want
something ready-to-use even if not yet in mainline, I would recommend
you to have a look at
https://github.com/MISL-EBU-System-SW/mainline-public/tree/backport-3.8.
This is a 3.8 vanilla kernel into which we have backported a number of
features/fixes, including the PCIe support.

We're hoping to get PCIe support in mainline for 3.11.

Best regards,

Thomas

Sorry I'm not yet very familiar with all this (patches, repos, 
backports, branches, ...).
I'll give a try to the backport you suggest and, hopefully, get back to 
you with some feedback.

Cheers,
