As Renesas ARM SoCs contain the following revisions: - SH-Mobile AG5: r3p1, - R-Mobile A1: r3p1-50rel0, - R-Car H1: r3p2, - RZ/A1: r3p2, - RZ/A2: r3p3, none of them are affected, and support for the errata can be disabled safely. The EMMA Mobile EV2 documentation doesn't mention the revision of its PL310 cache controller, so this SoC might be affected. However, the L2 cache controller is not enabled by Linux.
