a5ds only has always-on power domain and there is no power control
present. However, without the pwr_domain_off handler, the kernel
panics when the user will try to switch off secondary cores. The
a5ds_pwr_domain_off handler will prevent kernel from crashing,
i.e. the kernel will attempt but fail to shut down the secondary CPUs
if the user tries to switch them offline.

This patch adds mapping for secure FLASH0 for qemu/virt and
qemu/qemu_sbsa platforms. This change is targeted for sbsa but since both
platforms share common code, changes in common defines was necessary.

For qemu_sbsa, this patch adds necessary mapping in order to boot without
semi-hosting from secure FLASH0. EFI need to stay in FLASH1 (share it with
variables) since it need to "run in place" in non secure domain. Changes
for this are under RFC at edk2-platforms mailing list:
https://patches.linaro.org/patch/171327/


(edk2-platforms/Platform/Qemu/SbsaQemu/SbsaQemu.dsc).

In docs qemu/virt is described as using semi-hosting, therefore this change
should be orthogonal to existing assumptions while giving possibility to
store both bl1 and fip in FLASH0 at some point (additional changes required
for that).

Documentation is aligned to rest of SBSA patches along the series and
planed changes in edk2-platform repo.

This patch changes implementation for disabling Secure Cycle
Counter. For ARMv8.5 the counter gets disabled by setting
SDCR.SCCD bit on CPU cold/warm boot. For the earlier
architectures PMCR register is saved/restored on secure
world entry/exit from/to Non-secure state, and cycle counting
gets disabled by setting PMCR.DP bit.
In 'include\aarch32\arch.h' header file new
ARMv8.5-PMU related definitions were added.

This patch invokes the new function gicv3_rdistif_probe() in the
ARM platform specific gicv3 driver. Since this API modifies the
shared GIC related data structure, it must be invoked coherently
by using the platform specific pwr_domain_on_finish_late hook.

This PSCI hook is similar to pwr_domain_on_finish but is
guaranteed to be invoked with the respective core and cluster are
participating in coherency. This will be necessary to safely invoke
the new GICv3 API which modifies shared GIC data structures concurrently.

This patch provides declaration and definition of new GICv3 driver
API: gicv3_rdistif_probe().This function delegates the responsibility
of discovering the corresponding Redistributor base frame to each CPU
itself. It is a modified version of gicv3_rdistif_base_addrs_probe()
and is executed by each CPU in the platform unlike the previous
approach in which only the Primary CPU did the discovery of all the
Redistributor frames for every CPU.

The flush operations as part of gicv3_driver_init() function are
made necessary even for platforms with WARMBOOT_ENABLE_DCACHE_EARLY
because the GICv3 driver data structure contents are accessed by CPU
with D-Cache turned off during power down operations.

As the Raspberry Pi4 port is now in a usable state, add the build
instructions together with some background information to the
documentation directory.
The port differs quite a bit from the Raspberry Pi 3, so we use a
separate file for that.

Some device tree users like to find a pointer to the standard serial
console in the device tree, in the "stdout-path" property of the /chosen
node.

Add the location of the Mini UART in that property, so that DT users are
happy, for instance Linux' earlycon detection.

For being able to use the virtualisation support the GIC offers, we need
to know the interrupt number of the maintenance interrupt. This
information is missing from the official RPi4 device tree.

Use libfdt to add the "interrupts" property to the GIC node, which
allows hypervisors like KVM or Xen to be able to use the GIC's help on
virtualising interrupts.

Now that we have the SMP pens in the first page of DRAM, we can get rid
of all the fancy RPi3 memory regions that our RPi4 port does not really
need. This avoids using up memory all over the place, restricting ATF
to just run in the first 512KB of DRAM.

Remove the now unused regions. This also moves the SMP pens into our
first memory page (holding the firmware magic), where the original
firmware put them, but where there is also enough space for them.

Since the pens will require code execution privileges, we amend the
memory attributes used for that page to include write and execution
rights.
