Yes indeed this SoC support LPAE.Well Armada XP supports LPAE but don't use any outer cache functions, he works with the Aurora cache controller on 'system cache'. Armada 370 uses this outer cache functions but doesn't support LPAE.Can the Armada 370 be configured to use the co-processor interface to the L2, or does only the Armada XP support that feature? What happens if you build a single zImage supporting both of the SoCs?
About L2 cache we already use the same kernel on Armada 370 and Armada XP and the differences are in the device tree. Now if I understood correctly what the LPAE involved, I guess we can't have a kernel with LAPE running on Armada 370.
