Updated the code to get and set the 'tpm_event_log_max_size' property
in the event_log.dtsi.
In this change, the maximum Event Log buffer size allocated by BL1 is
passed to BL2, rather than both relying on the maximum Event Log buffer
size macro.

Add initial configuration parameters for Rasperry Pi 3's sdhost
controller, and then configure and use those parameters.
This change allows warm reboots of UEFI on Raspberry Pi 3B+ where
existing code often fails with "unknown error". See discussion at:
https://github.com/pftf/RPi3/issues/24
The basic idea is that some initial configuration parameters
(clock rate, bus width) aren't configured into the hardware before
commands start being sent. I suspect that the particular setting
that matters is the "slow card" bit, but the initial clock setting
also seemed wrong to me.

The value of register HCRX_EL2 is UNKNOWN out of reset. This can
affect the behavior in lower exception levels, such as traps to
EL2 due to a wrong configuration of the register upon reset.
This patch initializes the register at EL3 and disables all traps
related to it.
On the other hand, new fields have been introduced for HCRX_EL2,
which are now defined in this patch, so they can be used in
further development.

Arm v8.9 introduces a series of features providing a new way to set memory
permissions. Instead of directly encoding the permissions in the page
tables the PTEs contain indexes into an array of permissions stored in
system registers, allowing greater flexibility and density of encoding.
Enable access to these features for EL2 and below, context switching the
newly added EL2 registers as appropriate. Since all of FEAT_S[12]P[IO]E
are separately discoverable we have separate build time options for
enabling them, but note that there is overlap in the registers that they
implement and the enable bit required for lower EL access.
Change the FVP platform to default to handling them as dynamic options so
the right decision can be made by the code at runtime.

When porting TF-A to a new platform, it is essential to read the
threat model documents in conjunction with the porting guide to
understand the security responsibilities of each platform interface
to implement.
Add a note to highlight this in the porting guide.

The porting guide is currently hosted under the 'Getting started'
section. Yet, porting the full firmware to a new platform is probably
not the first thing that one would do. Before delving into the
details, one would probably start by building the code for an emulated
platform, such as Arm FVP.
Furthermore, the porting guide is such a big and important document
that it probably deserves being visible in the main table of contents.
Thus, move it just above the list of supported platforms.

There is a use case where kernel requested ATF to power off/on only CPU0.
However, after ATF power off/on CPU0, CPU0 did not back into the state
to wait for ATF. Instead, CPU0 continue to reentry SPL boot sequence
because CPU0 is master/primary core. This causing the system reboot from
SPL again, while the slave core still in kernel.
To resolve this, ATF is set the boot scratch register 8 bit 17 whenever
it is a request from kernel to power off/on only CPU0. So, if this boot
scratch bit is set, CPU 0 will be able to put into a state to wait for
ATF.

when they are not used / not referenced.
If the board device tree only defines subnodes, dtc does not consider it
as usage, you have to specifically mention device's phandle, e.g.:
\ {
i2c6-phandle = <&i2c6>;
};
or in aliases section

Qemu-tcg with GICv3 emulation enabled will by default configure MPIDR
topology to report up to 16 cpus per cluster. This is NOT overriden by
qemu's -smp setting, e.g. -smp 8,clusters=2,cores=4,threads=1 will still
generate MPIDR reads as if all 8 CPUs were within one cluster.
Increase the hardcoded limit to reflect that so that we accept PSCI
calls that provide MPIDRs based on what was actually read from the
emulated CPU.
