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.

The commit a6485b2b3b ("refactor(delay-timer): add timer

timer ops structure. Fix it by moving generic delay timer init
prior to console setup to make sure that time is setup before DCC
console setup.

FEAT_MOPS, mandatory from Arm v8.8, is typically managed in EL2.
However, in configurations where NS_EL2 is not enabled,
EL3 must set the HCRX_EL2.MSCEn bit to 1 to enable the feature.
This patch ensures FEAT_MOPS is enabled by setting HCRX_EL2.MSCEn to 1.

For a couple of releases now we have officially withdrawn support for
building TF-A on Windows using the native environment, relying instead
on POSIX emulation layers like MSYS2, Mingw64, Cygwin or WSL.
This change removes the remainder of the OS compatibility layer
entirely, and migrates the build system over to explicitly relying on a
POSIX environment.

Initializing all early clocks before the MMU is enabled can impact boot
time. Therefore, splitting the setup into A53 clocks and peripheral
clocks can be beneficial, with the peripheral clocks configured after
fully initializing the MMU.

On some platforms plat_my_core_pos is a nontrivial function that takes a
bit of time and the compiler really doesn't like to inline. In the PSCI
library, at least, we have no need to keep repeatedly calling it and we
can instead pass it around as an argument. This saves on a lot of
redundant calls, speeding the library up a bit.

psci_suspend_to_standby_finisher and psci_cpu_suspend_finish do mostly
the same stuff, besides the system management associated with their
respective wakeup paths. So bring the wake from standby path in line
with the wake from reset path - caller acquires locks and manages
context. This way both behave in vaguely the same way. We can also bring
their names in line so it's more apparent how they are different.
This is in preparation for cores waking from sleep, coming in another
patch. No functional change is expected.

The target_pwrlvl field in the psci cpu data struct only stores the
highest power domain that a CPU_SUSPEND call affected, and is used to
resume those same domains on warm reset. If the cpu is otherwise OFF
(never turned on or CPU_OFF), then this needs to be the highest power
level because we don't know the highest level that will be off.
So skip the invalidation and always keep the field to the maximum value.
During suspend the field will be lowered to the appropriate value and
then put back after wakeup.
Also, do that in the suspend to standby path as well as it will have
been written before the sleep and it might end up incorrect.

Patch fc7dca72ba656e5f147487b20f9f0fb6eb39e116 changed the owning
security states of the TRBE and SPE buffers to NS. The thinking was that
this would assist SMCCC feature availability to more easily determine
if the feature is enabled or disabled. However, that only changed bit 0
while the SMCCC feature only looks at bit 1 so this change is redundant.
It was also meant to tighten security but that was done by
73d98e3759 instead.
Annoyingly, FEAT_TRBE has TRBIDR_EL1 which reports that programming is
allowed when the current security state owns the buffer even when the
MDCR_EL3 setting disallows this in practice.
So revert the functional aspect of the patch as it causes linux panics
with ERRATA_A520_2938996. Keep the defines as they are used elsewhere.
