From: Suzuki K Poulose <suzuki.poulose@arm.com> commit c0b15c25d25171db4b70cc0b7dbc1130ee94017d upstream. The erratum 1024718 affects Cortex-A55 r0p0 to r2p0. However we apply the work around for r0p0 - r1p0. Unfortunately this won't be fixed for the future revisions for the CPU. Thus extend the work around for all versions of A55, to cover for r2p0 and any future revisions.
