I think this would be great if it also had:

CONFIG_ARCH_VIRT=y
CONFIG_VIRTUALIZATION=y
CONFIG_KVM=y

That would allow it to be used for KVM testing both as host and guest.

FWIW, I just tried booting this on my TC2, but I don't get any output
from there.  Is it supposed to work on this platform?  If not, why not?

Thanks,
-Christoffer

[Alison Wang] One question, does TC2 support LPAE? If so, we could try to
find the reason and add it in this defconfig for armv7 LPAE support.

Yes, I think we should enable all platforms that we enable in the normal
multi_v7_defconfig, if we decide to add a new one. Just remove the platforms
that are based on Cortex-A5/A8/A9, Scorpion or PJ4 rather than A7/A12/A15/A17
or Krait.

[Alison Wang] Thanks for your advice. I will try to prepare a new one according
to your advice.
