| H A D | neoverse_n2.S | 0d2d99924e1be548e75c46cfd536f7503cf863e0 Thu Oct 21 00:30:46 UTC 2021 nayanpatel-arm <nayankumar.patel@arm.com> fix(errata): workaround for Neoverse-N2 erratum 2280757
Neoverse-N2 erratum 2280757 is a Cat B erratum that applies to
revision r0p0 of CPU. It is still open. The workaround
is to set CPUACTLR_EL1[22] to 1'b1. Setting CPUACTLR_EL1[22]
will cause CFP instruction to invalidate all branch predictor
resources regardless of context.
