[Alison Wang] Because PCIE, IFC region 2, DRAM2 and other IPs on LS1021A
are in the 40-bit address space, so we need to enable LPAE to access those
memory beyond the 4GB limit.

Let me summarize the current status. I have made multi_v7_lpae_defconfig to
support LS1021A according to the suggestion from Russell King. Olof Johansson
said they have discussed it before and they have chosen to just have a
multi_v7_defconfig. Attached is the discussion. There is not further
solution about the discussion.

So now, I suggest to remain LS1021A in multi_v7_defconfig at least.

Best Regards,
Alison Wang
