 For Cortex-A710, the following errata build flags are defined :
 
+-  ``ERRATA_A710_1901946``: This applies errata 1901946 workaround to
+   Cortex-A710 CPU. This needs to be enabled only for revision r1p0. It has
+   been fixed in r2p0.
+
 -  ``ERRATA_A710_1987031``: This applies errata 1987031 workaround to
    Cortex-A710 CPU. This needs to be enabled only for revisions r0p0, r1p0 and
    r2p0 of the CPU. It is still open.
