 * This file provides desired ordering for Exynos5420 and Exynos5800
 * boards: CPU[0123] being the A15.
 *
 * 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.
