Description: Neoverse-N2: 2253138: workaround TRBE writing to address out-of-range

More info: This option adds the workaround for ARM Neoverse-N2 erratum 2253138. Affected Neoverse-N2 cores might write to an out-of-range address, not reserved for TRBE. Under some conditions, the TRBE might generate a write to the next virtually addressed page following the last page of the TRBE address space (i.e., the TRBLIMITR_EL1.LIMIT), instead of wrapping around to the base. Work around this in the driver by always making sure that there is a page beyond the TRBLIMITR_EL1.LIMIT, within the space allowed for the TRBE. If unsure, say Y.
