Antonio Nino Diaz bd9344f670 plat/arm: Sanitise includes
Use full include paths like it is done for common includes.

This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

Antonio Nino Diaz 09d40e0e08 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: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("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.

Soby Mathew 7b56928a12 Juno: Change the Firmware update detect mechanism
Previously, Juno used to depend on the SSC_GPRETN register to inform
about the reset syndrome. This method was removed when SCP migrated
to the SDS framework. But even the SDS framework doesn't report the
reset syndrome correctly and hence Juno failed to enter Firmware
update mode if BL2 authentication failed.

In addition to that, the error code populated in V2M_SYS_NVFLAGS register
does not seem to be retained any more on Juno across resets. This could
be down to the motherboard firmware not doing the necessary to preserve
the value.

Hence this patch modifies the Juno platform to use the same mechanism to
trigger firmware update as FVP which is to corrupt the FIP TOC on
authentication failure. The implementation in `fvp_err.c` is made common
for ARM platforms and is moved to the new `arm_err.c` file in
plat/arm/common folder. The BL1 and BL2 mmap table entries for Juno
are modified to allow write to the Flash memory address.

Vikram Kanigiri 6355f2347a Rework use of interconnect drivers
ARM Trusted Firmware supports 2 different interconnect peripheral
drivers: CCI and CCN. ARM platforms are implemented using either of the
interconnect peripherals.

This patch adds a layer of abstraction to help ARM platform ports to
choose the right interconnect driver and corresponding platform support.
This is as described below:

1. A set of ARM common functions have been implemented to initialise an
interconnect and for entering/exiting a cluster from coherency. These
functions are prefixed as "plat_arm_interconnect_". Weak definitions of
these functions have been provided for each type of driver.

2.`plat_print_interconnect_regs` macro used for printing CCI registers is
moved from a common arm_macros.S to cci_macros.S.

3. The `ARM_CONFIG_HAS_CCI` flag used in `arm_config_flags` structure
is renamed to `ARM_CONFIG_HAS_INTERCONNECT`.

Yatharth Kochar 436223def6 FWU: Add Firmware Update support in BL1 for ARM platforms
This patch adds Firmware Update support for ARM platforms.

New files arm_bl1_fwu.c and juno_bl1_setup.c were added to provide
platform specific Firmware update code.

BL1 now includes mmap entry for `ARM_MAP_NS_DRAM1` to map DRAM for
authenticating NS_BL2U image(For both FVP and JUNO platform).

Dan Handley 3fc4124c75 Move FVP port to plat/arm/board/fvp
Move the FVP port from plat/fvp to plat/arm/board/fvp. Also rename
some of the files so they are consistently prefixed with fvp_.
Update the platform makefiles accordingly.
