Anders Dellien 3ab336a125 plat/arm: Add dependencies to configuration files
This patch adds dependencies to the generated configuration
files that are included in the FIP. This fixes occasional
build errors that occur when the FIP happens to be built first.

Madhukar Pappireddy fddfb3baf7 plat/arm: Use common build flag for using generic sp804 driver
SP804 TIMER is not platform specific, and current code base adds
multiple defines to use this driver. Like FVP_USE_SP804_TIMER and
FVP_VE_USE_SP804_TIMER.

This patch removes platform specific build flag and adds generic
flag `USE_SP804_TIMER` to be set to 1 by platform if needed.

Alexei Fedorov 1322dc94f7 TF-A GICv2 driver: Introduce makefile
This patch moves all GICv2 driver files into new added
'gicv2.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.

NOTE: Usage of 'drivers/arm/gic/common/gic_common.c' file
is now deprecated and platforms with GICv2 driver need to
be modified to include 'drivers/arm/gic/v2/gicv2.mk' in
their makefiles.

Manish V Badarkhe 3cb84a5425 plat/arm: Rentroduce tb_fw_config device tree
Moved BL2 configuration nodes from fw_config to newly
created tb_fw_config device tree.

fw_config device tree's main usage is to hold properties shared
across all BLx images.
An example is the "dtb-registry" node, which contains the
information about the other device tree configurations
(load-address, size).

Also, Updated load-address of tb_fw_config which is now located
after fw_config in SRAM.

Louis Mayencourt a6de824f7e fconf: Clean Arm IO
Merge the previously introduced arm_fconf_io_storage into arm_io_storage. This
removes the duplicate io_policies and functions definition.

This patch:
- replace arm_io_storage.c with the content of arm_fconf_io_storage.c
- rename the USE_FCONF_BASED_IO option into ARM_IO_IN_DTB.
- use the ARM_IO_IN_DTB option to compile out io_policies moved in dtb.
- propagate DEFINES when parsing dts.
- use ARM_IO_IN_DTB to include or not uuid nodes in fw_config dtb.
- set the ARM_IO_IN_DTB to 0 by default for fvp. This ensure that the behavior
  of fvp stays the same as it was before the introduction of fconf.

Louis Mayencourt 25ac87940c fconf: Add dynamic config DTBs info as property
This patch introduces a better separation between the trusted-boot
related properties, and the dynamic configuration DTBs loading
information.

The dynamic configuration DTBs properties are moved to a new node:
`dtb-registry`. All the sub-nodes present will be provided to the
dynamic config framework to be loaded. The node currently only contains
the already defined configuration DTBs, but can be extended for future
features if necessary.
The dynamic config framework is modified to use the abstraction provided
by the fconf framework, instead of directly accessing the DTBs.

The trusted-boot properties are kept under the "arm,tb_fw" compatible
string, but in a separate `tb_fw-config` node.
The `tb_fw-config` property of the `dtb-registry` node simply points
to the load address of `fw_config`, as the `tb_fw-config` is currently
part of the same DTB.

Louis Mayencourt 3b5ea741fd fconf: Load config dtb from bl1
Move the loading of the dtb from arm_dym_cfg to fconf. The new loading
function is not associated to arm platform anymore, and can be moved
to bl_main if wanted.

Ambroise Vincent 37b70031e0 arm: Shorten the Firmware Update (FWU) process
The watchdog is configured with a default value of 256 seconds in order
to implement the Trusted Board Boot Requirements.

For the FVP and Juno platforms, the FWU process relies on a watchdog
reset. In order to automate the test of FWU, the length of this process
needs to be as short as possible. Instead of waiting for those 4 minutes
to have a reset by the watchdog, tell it to reset immediately.

There are no side effects as the value of the watchdog's load register
resets to 0xFFFFFFFF.

Tested on Juno.

Usama Arif 6393c787b5 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.
