7 * This file provides desired ordering for Exynos5420 and Exynos5800
8 * boards: CPU[0123] being the A15.
9 *
10 * The Exynos5420, 5422 and 5800 actually share the same CPU configuration
11 * but particular boards choose different booting order.
12 *
13 * Exynos5420 and Exynos5800 always boot from Cortex-A15. On Exynos5422
14 * booting cluster (big or LITTLE) is chosen by IROM code by reading
15 * the gpg2-1 GPIO. By default all Exynos5422 based boards choose booting
16 * from the LITTLE: Cortex-A7.
