[Alison Wang] Thanks for your reply. I tried to make this multi_v7_lpae_defconfig
according to the discussion with Russell King. He suggested to make a multi_v7_lpae_defconfig
rather than creating a new load of platform specific defconfigs. Attached is his original email.

King, do you have any comment about Olof's reply?


Best Regards,
