There is no need to rely on x1 argument.

The argument passed via x1 is used as a base address for comphy related
routines. Nevertheless validation of this address wasn't good enough and
allowed some non comphy related addresses to slip over.

To overcome this issue make sure that the address passed via SMC points
to valid CP range and allow to proceed comphy initializations only with
correct comphy offset.

This could be fixed in a different way e.g. by passing CP id from the
caller, but since this API is already used with various Linux, U-Boot
and UEFI versions it can't be changed.

Many parts of the code were duplicating symbols that are defined in
include/common/bl_common.h. It is better to only use the definitions in
this header.

As all the symbols refer to virtual addresses, they have to be
uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

The definitions in bl1/bl1_private.h and bl2/bl2_private.h are useful for
platforms that may need to access them.

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

In Armada 8K DB boards, PCIe initialization can be executed only once
because PCIe reset performed during chip power on and it cannot be
executed via GPIO later.
This means that power on can be executed only once, when it's called
from the bootloader.
Power on:
	Read bit 21 of the mode, it marks if the caller is
	the bootloader or the Linux Kernel.
Power off:
	Check if the comphy was already configured to PCIe, if yes,
	check if the caller is bootloader, if both conditions are true
	(PCIe mode and called by Linux) - skip the power-off.

In addition, fix incorrect documentation describing mode fields -
PCIe width is 3 bits, not 2.

NOTE: with this patch, please use LK4.14.76 (LK4.4.120 may not work
with it).

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

Even though at this point plat_crash_console_flush is optional, it will
stop being optional in a following patch.

The console driver of warp7 doesn't support flush, so the implementation
is a placeholder.

TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but
they weren't global so they weren't actually used. Also, they were
calling the wrong functions.

imx8_helpers.S only has placeholders for all of the functions.

The "Secure" prefix (S-ELx) is valid only for S-EL0 and S-EL1 but is
meaningless for EL3, since EL3 is always secure. Hence, the "S" prefix
has been removed from wherever it was used as "S-EL3".

- Fix build issue
- Add initial memory parameters descriptors for BL2
- Migrate to image load V2

Need to fix the service CPU (CM3) image load procesure and test

This patch enables handling PMU overflow IRQ by GIC SPI's
directly in EL3. Also implement additional SMC routine,
which can disable the solution on demand in runtime.

Since it is possible to configure PMU interrupt trigger type
in the MADT ACPI table, it is enough to set it only once in EL3
during initialization.
