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.
