Only one platform supported in "multi_v7" config?

looking at at kernelci boots with CONFIG_LPAE=y:

http://kernelci.org/build/mainline/kernel/v4.3/defconfig/multi_v7_defconfig+CONFIG_ARM_LPAE=y/?_id=5636b71c59b5145a2d3af14a

At least MVEBU, EXYNOS5, HISI, OMAP5, SUNXI, TEGRA and VEXPRESS need
to be enabled. Also all drivers needed to boot these platforms.
Perhaps the better approach would be to start with multi_v7_defconfig
and remove each ARCH/MACH that doesn't have an LPAE capable CPU in th
family.
