The workarounds for these below mentioned errata are not implemented in EL3, but the flags can be enabled/disabled at a platform level based on arm/non-arm interconnect IP flag. The ABI helps assist the Kernel in the process of mitigation for the following errata: Cortex-A715: erratum 2701951 Neoverse V2: erratum 2719103 Cortex-A710: erratum 2701952 Cortex-X2: erratum 2701952 Neoverse N2: erratum 2728475 Neoverse V1: erratum 2701953 Cortex-A78: erratum 2712571 Cortex-A78AE: erratum 2712574 Cortex-A78C: erratum 2712575 Change-Id: Ie86b7212d731a79e2a0c07649e69234e733cd78d Signed-off-by: Sona Mathew <sonarebecca.mathew@arm.com>
