The configuration of the FIPS alter the SoC which is configured
and cannot be reverted so the support SHALL NOT be in
customer binary as it could lead to DoS of the SECO.
We add a SIP service to configure the FIPS mode. It is added
to the ATF because it is the only component with the required
permissions to successfully perform the call.
This service currently only allow to set the FIPS mode with
a value but can be extended.
IT can be called from other components like uboot or the OS.
The support is added only if the bl31 is compiled with
FIPS_CONFIG defined which happens when FIPS_CONFIG=on is passed
as option to Makefile.

8DX and 8QX share the same die,
so will reuse the same implementation

On iMX8 Rev A the OCRAM is used to pass over ROM info, and u-boot
needs to access it. So we can't assign the OCRAM to ATF partition.
This will cause boot hang.
Rev A does not support SPL, so it is ok to not protect the OCRAM.

NXP's i.MX8 SoCs with system controller inside support outputting
debug message to system controller's console via calling SCFW API,
since TF-A shares debug console with Linux kernel which will have
confliction if Linux kernel and TF-A's console are both enabled,
this patch adds support for switching TF-A debug console to system
controller to easy TF-A debug.

Platform defines are already provided by the build system so let's not
duplicate them.

The IMX_SIP_BUILDINFO call was implemented for imx8qm and imx8qx but
it's also applicable to imx8m.
This fixes U-Boot not printing commit hash on 8m with upstream TF-A.

Now it is needed to use the full path of the common header files.
Commit 09d40e0e0828 ("Sanitise includes across codebase") provides more
information.

This patch adds NXP i.MX8 SoCs' build info SIP support for easy debug.
With this function enabled, TF-A's commit hash can be showed in u-boot
debug console when booting up, when there is any issue which could be
related to TF-A, users can use the commit hash value to easily identify
which commit introduces the issue.

For NXP's i.MX8 SoCs with system controller inside, thermal sensors
are maintained by SCFW, Linux needs to call SMC to trap to TF-A for
thermal alarm operation etc. by calling SCFW API.
This patch adds temperature alarm SIP service support.

On i.MX8QM/i.MX8QX with system controller inside, the wakeup
source is managed in SCFW(system controller firmware), if the
wakeup source is belonged to system controller partition, then
before Linux suspend, the wakeup source should be set to
SC_PM_WAKE_SRC_SCU, and if the wakeup source is belonged to
Cortex-A partition, the wakeup source should be set to
SC_PM_WAKE_SRC_IRQSTEER, so need to add wakeup source SIP runtime
service to get Linux kernel's wakeup source and set the correct
wakeup source for system controller.

On i.MX8QM/i.MX8QX with system controller inside, the CPU's clock
rate is managed by SCFW(system controller firmware) and can ONLY be
changed from secure world, so SIP runtime service is needed for
setting CPU's clock rate, this patch adds cpu-freq SIP runtime service
support.

On i.MX8QM/i.MX8QX with system controller inside, the SRTC is
managed by SCFW(system controller firmware) and some functions
like setting SRTC's time etc. can ONLY be requested from secure
world, so SIP runtime service is needed for such kind of operations,
this patch adds SRTC SIP runtime service support for i.MX8QM and
i.MX8QX.
