H A Dcortex_a76.S55ff05f384aa8e150f192f618e807bab3e1ea12b Tue Sep 29 22:19:09 UTC 2020 johpow01 <john.powell@arm.com> Workaround for Cortex A76 erratum 1868343

Cortex A76 erratum 1868343 is a Cat B erratum, present in older
revisions of the Cortex A76 processor core. The workaround is to
set a bit in the CPUACTLR_EL1 system register, which delays instruction
fetch after branch misprediction. This workaround will have a small
impact on performance.

This workaround is the same as workarounds for errata 1262606 and
1275112, so all 3 have been combined into one function call.
