This may not work immediately: from 2012 to 2015, a lot of changes have
been made to Buildroot. So a configuration that was working with
Buildroot 2012.11 may not be directly usable with Buildroot 2015.05.

This is a reference to a Marvell-specific kernel defconfig.

and you're using a mainline 4.0.4 kernel, which obviously doesn't have
this Marvell-specific defconfig.

So you have to make a choice:

 * Either you use the mainline kernel, and the defconfig for Armada 38x
   is called mvebu_v7_defconfig.

 * Or you use Marvell specific kernel, in which case you need to change
   the Buildroot option giving the location of the kernel sources so
   that Buildroot fetches the Marvell specific kernel instead of the
   mainline one.

Best regards,

Thomas
