+ * This file provides desired ordering for Exynos5422: CPU[0123] being the A7.
+ *
+ * The Exynos5420, 5422 and 5800 actually share the same CPU configuration
+ * but particular boards choose different booting order.
+ *
+ * Exynos5420 and Exynos5800 always boot from Cortex-A15. On Exynos5422
+ * booting cluster (big or LITTLE) is chosen by IROM code by reading
+ * the gpg2-1 GPIO. By default all Exynos5422 based boards choose booting
+ * from the LITTLE: Cortex-A7.
