| 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. |
