Cortex A77 erratum 1925769 is a Cat B erratum, present in older
revisions of the Cortex A77 processor core. The workaround is to
set bit 8 in the ECTLR_EL1 register, there is a small performance cost
(<0.5%) for setting this bit.

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.

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.

Currently the feature test for the SPE extension requires the feature
bits in the ID_AA64DFR0 register to read exactly 0b0001.
However the architecture guarantees that any values greater than 0
indicate the presence of a feature, which is what we are after in
our spe_supported() function.
Change the comparison to include all values greater than 0.
This fixes SPE support in non-secure world on implementations which
include the Scalable Vector Extension (SVE), for instance on Zeus cores.

Currently our memset() implementation is safe, but slow. The main reason
for that seems to be the single byte writes that it issues, which can
show horrible performance, depending on the implementation of the
load/store subsystem.
Improve the algorithm by trying to issue 64-bit writes. As this only
works with aligned pointers, have a head and a tail section which
covers unaligned pointers, and leave the bulk of the work to the middle
section that does use 64-bit writes.
Put through some unit tests, which exercise all combinations of nasty
input parameters (pointers with various alignments, various odd and even
sizes, corner cases of content to write (-1, 256)).

As per latest mailing communication [1], we decided to
update AT speculative workaround implementation in order to
disable page table walk for lower ELs(EL1 or EL0) immediately
after context switching to EL3 from lower ELs.
Previous implementation of AT speculative workaround is available
here: 45aecff00
AT speculative workaround is updated as below:
1. Avoid saving and restoring of SCTLR and TCR registers for EL1
in context save and restore routine respectively.
2. On EL3 entry, save SCTLR and TCR registers for EL1.
3. On EL3 entry, update EL1 system registers to disable stage 1
page table walk for lower ELs (EL1 and EL0) and enable EL1
MMU.
4. On EL3 exit, restore SCTLR and TCR registers for EL1 which
are saved in step 2.
