The cpu booting of exynos5422 has been still broken since we discussed it in last year[1]. This patch is inspired from Odroid XU3 code (Actually, it was from samsung exynos vendor kernel)[2]. This weird reset code was founded exynos5420 octa cores series SoCs and only required for the first boot core is the Little core (Cortex A7). Some of the exynos5420 boards and all of the exynos5422 boards will require this code. There is two ways to check the little core is the first cpu. One is checking GPG2CON[1] GPIO value and the other is checking the cluster number of the first cpu. I selected the latter because it's more easier than the former.
