1184 | This option enables the workaround for the 751472 Cortex-A9 (prior | ||
1185 | to r3p0) erratum. An interrupted ICIALLUIS operation may prevent the | ||

1187 | operation is received by a CPU before the ICIALLUIS has completed, | ||
1188 | potentially leading to corrupted entries in the cache or TLB. | ||
