The addition to the range property is *only* needed because the NOR DT
node is added. The two are needed together, so splitting them would
make absolutely no sense.

The reason why for the other board is was done in two patches is
because at the time Ezequiel sent the patch for the NOR, we were not
using this common ranges = <...> property in the DT. The additional
entry in the ranges = <...> property should have been added when the DT
reorganization was merged with the NOR patch from Ezequiel, but it
was not done. So Ezequiel sent a fixup patch to fix this.

There's no need to repeat the same story for the NOR flash of the
Armada XP DB.

Again, PATCH 1/2 is a fix for something that exists in 3.10-rc, while
PATCH 2/2 is enabling a new device, so presumably, it should go in 3.11.

Best regards,

Thomas
