Can you explain why you need a separate defconfig, aside from imx_v6_v7_defconfig
and multi_v7_defconfig? Please put a reason into the description above,
as we normally try to have only one defconfig per machine directory.

Does this machine require LPAE to function correctly?

LS1021A is different from I.MX. Also it has some special configure 
options. So it needs a separate defconfig.

Yes, we need it to access 40-bit address space, such as PCIE.

Hi Arnd,

I have verified that if we want to use multi_v7_defconfig to boot 
LS1021A up, we need add below configurations:
+CONFIG_THUMB2_KERNEL=y
+CONFIG_VMSPLIT_2G=y
+CONFIG_VFP=y.

If we add those to multi_v7_defconfig, it may destroy other platforms.
