Neoverse-N2 erratum 2326639 is a Cat B erratum that applies to revision
r0p0 and is fixed in r0p1. The workaround is to set CPUACTLR2_EL1[36] to
1 before the power down sequence that sets CORE_PWRDN_EN. This allows
the cpu to retry the power down and prevents the deadlock. TF-A never
clears this bit even if it wakes up from the wfi in the sequence since
it is not expected to do anything but retry to power down after and the
bit is cleared on reset.

Cortex-A78C erratum 2376749 is a Cat B erratum that applies

The workaround is to set CPUACTLR2_EL1[0] to 1 to force
PLDW/PFRM ST to behave like PLD/PRFM LD and not cause
invalidations to other PE caches.

r0p0, r1p0, and r2p0, and is fixed in r2p1. The workaround is to set

Setting this bit, along with these instructions will prevent the

OpenSSL 3.0 is a pre-requisite since v2.7 and can be installed
on the operating system by updating the previous version.
However, this may not be convenient for everyone, as some may
want to keep their previous versions of OpenSSL.
This update on the docs shows that there is an alternative to
install OpenSSL on the system by using a local build of
OpenSSL 3.0 and pointing both the build and run commands to
that build.

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.
