| H A D | cortex_a710.S | 3280e5e655ad64b6e299e18624d9c586e6b37cb1 Thu Jul 21 14:25:08 UTC 2022 Akram Ahmad <Akram.Ahmad@arm.com> fix(errata): workaround for Cortex-A710 erratum 2147715
Cortex-A710 erratum 2147715 is a Cat B erratum that applies
to revision r2p0 of the CPU, and is fixed in r2p1. The work-
around is to set CPUACTLR_EL1[22]=1. Setting this will cause
the CFP instruction to invalidate all branch predictor resources
regardless of the context.
