Hello,

I am trying to set the Nand in a CM-510 Compulab based board (4.0-rc5).

As pxa3xx-nand driver supports NFCv1 (PXA3xx) and NFCv2 (Armada 370/XP), 
  I think that it should work more or less with Dove SoC (NFCv1) that is 
similar enough.

Until now, I've only added the correspondent node in dove.dtsi and the 
partitions in dove-cm-a510.dts ( it should be updated in the patch 
series that Sebastian Hesselbarth submitted ) :
