Can you check after applying following two patches for Arndale-Octa
([1],[2])? In other words, a patch similar to [2] might be required
for this board too if it is booting under secure mode.

[PATCH v2 Resend 1/2] ARM: EXYNOS: Update secondary boot addr for secure mode

[PATCH v2 Resend 2/2] ARM: dts: Add secure firmware support for Arndale-octa
