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. | |
