Subject: [PATCH] Tegra210: enable errata for Cortex-A57 and Cortex-A53 CPUs
This patch enables the following erratas for the Tegra210 SoC:
* Cortex-A57
=============
- A57_DISABLE_NON_TEMPORAL_HINT
- ERRATA_A57_826974
- ERRATA_A57_826977
- ERRATA_A57_828024
- ERRATA_A57_829520
- ERRATA_A57_833471
* Cortex-A53
=============
- A53_DISABLE_NON_TEMPORAL_HINT
- ERRATA_A53_826319
- ERRATA_A53_836870
Tegra210 uses Cortex-A57 revision: r1p1 and Cortex-A53 revision: r0p2.
