3.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stephen Warren <redacted> commit f35b431dde39fb40944d1024f08d88fbf04a3193 upstream. The ARM IP revisions in Tegra are: Tegra20: CPU r1p1, PL310 r2p0 Tegra30: CPU A01=r2p7/>=A02=r2p9, NEON r2p3-50, PL310 r3p1-50 Based on work by Olof Johansson, although the actual list of errata is somewhat different here, since I added a bunch more and removed one PL310 erratum that doesn't seem applicable.
