From c44bb3a30f5a1332176edce1a91c0e2cf666ee8f Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 26 Feb 2013 12:28:28 +0000 Subject: ARM: tegra: enable some CPU errata workarounds Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such, some CPU errata exist, and must be worked around. These must be worked around in the bootloader, since in general, the kernel (especially a multi-platform kernel) needs to support being launched in non-secure mode (normal world), and hence may not be able to write to the CP15 register to enable these workarounds.
