Cortex A78 AE erratum 2395408 is a Cat B erratum that applies
to revisions <= r0p1. It is still open.
This erratum states, "A translation table walk that matches an
existing L1 prefetch with a read request outstanding on CHI might
fold into the prefetch, which might lead to data corruption for
a future instruction fetch"
This erratum is avoided by setting CPUACTLR2_EL1[40] to 1 to
disable folding of demand requests into older prefetches with
L2 miss requests outstanding.

Cortex A78 AE erratum 2376748 is a Cat B erratum that applies
to revisions <= r0p1. It is still open.
The erratum states, "A PE executing a PLDW or PRFM PST instruction
that lies on a mispredicted branch path might cause a second PE
executing a store exclusive to the same cache line address to fail
continuously."
The erratum is avoided by setting CPUACTLR2_EL1[0] to 1 to force
PLDW/PFRM ST to behave like PLD/PRFM LD and not cause invalidations
to other PE caches. There might be a small performance degradation
to this workaround for certain workloads that share data.

header, increasing the size of the header to 512 bytes (0x200).
This header will be placed at the end of SRAM3 by BootROM, letting

The boot context is now placed in SRAM2, hence this memory has to be
mapped in BL2 MMU. This mapping is done for all SRAMs in a 2MB area.

This patch applies CVE-2022-23960 workarounds for Cortex-A75,
Cortex-A73, Cortex-A72 & Cortex-A57. This patch also implements
the new SMCCC_ARCH_WORKAROUND_3 and enables necessary discovery
hooks for Coxtex-A72, Cortex-A57, Cortex-A73 and Cortex-A75 to
enable discovery of this SMC via SMC_FEATURES. SMCCC_ARCH_WORKAROUND_3
is implemented for A57/A72 because some revisions are affected by both
CVE-2022-23960 and CVE-2017-5715 and this allows callers to replace
SMCCC_ARCH_WORKAROUND_1 calls with SMCCC_ARCH_WORKAROUND_3. For details
