Hello, The Armada XP SoCs have LPAE support. This patch set allow to run kernel on this SoCs with LPAE support.
The biggest changes are the conversion of the device tree file to 64 bits in order to be able to use more than 4GB of memory (without this the LPAE is pointless). This patch set have been tested on a Armada XP GP board with 8GB of DRAM with LPAE selected. It have been tested on Armada XP DB board with 3GB of DRAM with and without LPAE. And also on the Armada 370 DB board (without LPAE) to check that no regression appeared. This patch set is based on 3.9-rc3 and is 3.10 material. The git branch called lpae is available at: https://github.com/MISL-EBU-System-SW/mainline-public.git.
