* 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.
