lib/fconf: Update 'set_fw_config_info' function
...
Updated the function 'set_fw_config_info' to make it generic
by doing below changes:
1. Rename function name from 'set_fw_config_info' to 'set_config_info'
2. Take image_id as an argument so that this function can set any
config information.

plat/arm: Check the need for firmware update only once
...
Currently, the need for firmware update is being checked twice
in the code hence modifications are done to do this check only
once and set the global variable.
Then this global variable helps to decide whether to go for
normal boot or firmware update flow.

Modified the code to do below changes:
1. Load tb_fw_config along with fw_config by BL1.
2. Populate fw_config device tree information in the
BL1 to load tb_fw_config.
3. In BL2, populate fw_config information to retrieve
the address of tb_fw_config and then tb_fw_config
gets populated using retrieved address.
4. Avoid processing of configuration file in case of error
value returned from "fw_config_load" function.
5. Updated entrypoint information for BL2 image so
that it's arg0 should point to fw_config address.

Modified the code to do below changes:
1. Migrates the Arm platforms to the API changes introduced in the
previous patches by fixing the fconf_load_config() call.
2. Retrieve dynamically the address of tb_fw_config using fconf

address and BL2 hash data in the tb_fw_config DTB.

Switch AARCH32/AARCH64 to __aarch64__
...
NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.
All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)

plat/arm: introduce wrapper functions to setup secure watchdog
...
The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.
So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.

plat/arm: Introduce FVP Versatile Express platform.
...
This patch adds support for Versatile express FVP (Fast models).
Versatile express is a family of platforms that are based on ARM v7.
Currently this port has only been tested on Cortex A7, although it
should work with other ARM V7 cores that support LPAE, generic timers,
VFP and hardware divide. Future patches will support other
cores like Cortex A5 that dont support features like LPAE
and hardware divide. This platform is tested on and only expected to
work on single core models.

plat/arm: Fix header dependencies

From now on, platform_def.h must include any header with definitions that
are platform-specific (like arm_def.h) and the included headers mustn't
include back platform_def.h, and shouldn't be used by other files. Only
platform_def.h should be included in other files. This will ensure that all
needed definitions are present, rather than needing to include all the
headers in all the definitions' headers just in case.
This also prevents problems like cyclic dependencies.

Sanitise includes across codebase
...
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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("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.

xlat: Fix compatibility between v1 and v2
...
There are several platforms using arm_setup_page_tables(), which is
supposed to be Arm platform only. This creates several dependency
problems between platforms.
This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib
v2 makefile. This way it is possible to detect from C code which version
is being used and include the correct header.
The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and
moved to a common folder. This way, when in doubt, this header can be
used to guarantee compatibility, as it includes the correct header based
on XLAT_TABLES_LIB_V2.
This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so
that is now locked in xlat lib v2) and ZynqMP (where it was added as a
workaround).

juno: Revert FWU update detect mechanism
...
The patch 7b56928 unified the FWU mechanism on FVP and Juno
platforms due to issues with MCC firmware not preserving the
NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
writing to the NOR flash while executing from the same flash
in Bypass mode had some stability issues. Hence, since the
MCC firmware issue is resolved, this patch reverts to the
NVFLAGS mechanism to detect FWU. Also, with the introduction
of SDS (Shared Data Structure) by the SCP, the reset syndrome
needs to queried from the appropriate SDS field.
