Thank you for testing.

Yes. Right you are. There is no ARCH_EXYNOS defined in multi_v7_defconfig
at current state (branch: for-next commit: ca610da Merge branch
'v3.16-next/dt-samsung-3' into for-next).
So booting kernel on 5410 SoC is not possible with multi_v7_defconfig.
Please use exynos_defconfig.
