If I understood well a version 2 is expected. If I missed it, please
point me on it.

Once the binding will be acked I will be able to apply the dts
patch. For the first patch unless I am wrong the the series "EDAC
drivers for Armada XP L2 and DDR" was not applied or even formally
acked. Also while you will be at sending a new version please add a
commit log even a simple one.

For the 3rd patch, I also wait the new version of patch 2 with an
ack.

Thanks,

Gregory
