MPMM is a core-specific microarchitectural feature. It has been present
in every Arm core since the Cortex-A510 and has been implemented in
exactly the same way. Despite that, it is enabled more like an
architectural feature with a top level enable flag. This utilised the
identical implementation.
This duality has left MPMM in an awkward place, where its enablement
should be generic, like an architectural feature, but since it is not,
it should also be core-specific if it ever changes. One choice to do
this has been through the device tree.
This has worked just fine so far, however, recent implementations expose
a weakness in that this is rather slow - the device tree has to be read,
there's a long call stack of functions with many branches, and system
registers are read. In the hot path of PSCI CPU powerdown, this has a
significant and measurable impact. Besides it being a rather large
amount of code that is difficult to understand.
Since MPMM is a microarchitectural feature, its correct placement is in
the reset function. The essence of the current enablement is to write
CPUPPMCR_EL3.MPMM_EN if CPUPPMCR_EL3.MPMMPINCTL == 0. Replacing the C
enablement with an assembly macro in each CPU's reset function achieves
the same effect with just a single close branch and a grand total of 6
instructions (versus the old 2 branches and 32 instructions).
Having done this, the device tree entry becomes redundant. Should a core
that doesn't support MPMM arise, this can cleanly be handled in the
reset function. As such, the whole ENABLE_MPMM_FCONF and platform hooks
mechanisms become obsolete and are removed.

Ref: https://linaro.atlassian.net/browse/TFC-669
The initial LTS document was created as pdf and was maintained in a
shared folder location, to avoid pdf getting lost and trying to find
where it is we decided to have LTS details part of docs in TF-A.
This patch directly reflects the data from pdf attached to TFC-669.
Any improvements or amends to this will be done at later phases based
on LTS maintainers comments and agreements.

Create a new platform for the RD-1 AE automotive FVP.
This platform contains:
* Neoverse-V3AE, Arm9.2-A application processor
* A GICv4-compatible GIC-720AE
* 128 MB of SRAM, of which 1 MB is reserved for TF-A
and BL2 runs at ELmax (EL3).
Additionally, this commit updates the maintainers.rst file and
the changelog.yaml to add scope for RD-1 AE variants.

I originally added myself here because I had experience with the rk3399
code, when there were no other maintainers and that was the only
supported Rockchip SoC. Nowadays there are maintainers from the actual
manufacturer and most changes concern other SoCs, so I don't think it
makes sense for me to still be on here.

S32G274ARDB2 is a development board to showcase the capabilities of the
S32G2 SoC. It includes 4 ARM Cortex-A53 cores running at 1.0GHz, 4GBs
of DDR, accelerators for automotive networking and many other
peripherals.
The added support is minimal and only includes the BL2 stage, with no
MMU enabled. The FIP is preloaded by the BootROM in SRAM, and BL2 copies
BL31 and BL33 from FIP to their designated addresses.

Currently, neoverse_rd is hosted under the "css" directory. However,
"css" directory is more relevant for hosting css definitions and
corresponding sources. Since neoverse_rd hosts source and header for css
and soc, move neoverse_rd from css to board folder. Consolidate common
sources and headers under neoverse_rd/common. Additionally, group RD-V1,
RD-V1-MC, RD-N2, RD-N1-Edgex2 and SGI-575 within neoverse_rd/platform.

Currently, reference design platforms such as RD-N2, RD-N1-Edge,
RD-V1-MC, RD-V1 and SGI-575 utilize "css/sgi" as the common source
directory. The "sgi" prefix originated from the System Guidance for
Infrastructure (SGI) and was initially associated with the SGI-575
platform. However, subsequent platforms released were under the Neoverse
Reference Design product name.
To align with the Neoverse Reference Design nomenclature, rename the
common source directory from "css/sgi" to "css/neoverse_rd" and update
all file prefixes from "sgi" to "nrd."
