multi_v7_defconfig is not suitable for booting LS1021 as it needs LPAE.
Remove this option.

This needs a better explanation. Why do we need LPAE for this platform?

[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

I think that's fine for the time being. We are still looking for a good way to deal with LPAE configurations in general.
