This patch adds the errata management firmware interface for lower ELs to discover details about CPU erratum. Based on the CPU erratum identifier the interface enables the OS to find the mitigation of an erratum in EL3. The ABI can only be present in a system that is compliant with SMCCCv1.1 or higher. This implements v1.0 of the errata ABI spec. For details on all possible return values, refer the design documentation below: ABI design documentation: https://developer.arm.com/documentation/den0100/1-0?lang=en Signed-off-by: Sona Mathew <SonaRebecca.Mathew@arm.com> Change-Id: I70f0e2569cf92e6e02ad82e3e77874546232b89a
