Cortex-A710 erratum 2282622 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r2p0, and is fixed in r2p1. The workaround is to set
CPUACTLR2_EL1[0] to 1, which will force PLDW/PFRM ST to behave like
PLD/PRFM LD and not cause invalidations to other PE caches.

r0p0, r0p1, r0p2, r0p3 and r1p0 and is fixed in r1p1.
This erratum workaround is a bit different because it interacts with a
feature supported in TFA. The typical method of implementing an errata
workaround will not work in this case as the MPMM feature would just be
re-enabled by context management at every core power on after being
disabled by the errata framework. So in addition to disabling MPMM, this
workaround also sets a flag in the MPMM runtime framework indicating
that the feature should not be enabled even if ENABLE_MPMM=1.

It applies to revisions r0p0, r1p0, and r2p0 and is still open.
There are 2 ways this workaround can be accomplished, the first of
which involves executing a few additional instructions around MSR
writes to CPUECTLR when disabling the prefetcher. (see SDEN for
details)
However, this patch implements the 2nd possible workaround which sets
the prefetcher into its most conservative mode, since this workaround

Neoverse V1 erratum 1940577 is a Cat B erratum, present in some
revisions of the V1 processor core. The workaround is to insert a
DMB ST before acquire atomic instructions without release semantics.
This issue is present in revisions r0p0 - r1p1 but this workaround
only applies to revisions r1p0 - r1p1, there is no workaround for older
versions.

ELP processors can sometimes have different MIDR values or features so
we are adding the "_arm" suffix to differentiate the reference

Cortex A77 erratum 1946167 is a Cat B erratum that applies to revisions

revisions of the Cortex A76 processor core. The workaround is to

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

This patch allows the system to fallback to a default CPU library
in case the MPID does not match with any of the supported ones.
This feature can be enabled by setting SUPPORT_UNKNOWN_MPID build
option to 1 (enabled by default only on arm_fpga platform).
This feature can be very dangerous on a production image and
therefore it MUST be disabled for Release images.

The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3
memory system variant is used, there won't be any L3 cache,
snoop filter, and SCU logic present hence no system control register
will be present. Hence check SCU presence before accessing DSU register
for DSU_936184 errata.
