Thanks for your help. I'm probably misunderstanding what this patch does and how the errata effects the system, but the commit message says CA15 cores. The above R-Car Gen1 and r8a7740 SoCs are not using CA15 - instead they use CA9. Not sure if the errata still applies though. So either the commit message or the list of the SoCs need to be updated. Thanks, / magnus
