| Subject: ARM: tegra: select required CPU and L2 errata options |
| |
| From: Stephen Warren <swarren@nvidia.com> |
| |
| 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. |
