As you know, however, a new exynos5422 board will be added soon. The board also has same configuration of the gpio pin and booted cpu0 from a cortex-a7 core. BTW, booting of secondary cpus are still broken. Is there any progress of the patch[1]? This patch is also generated top of the patch with some fixes.
