Replace dts includes with C preprocessor syntax
...
Using the /include/ syntax, the include was evaluated by dtc, only after running
the preprocessor, therefore the .dtsi files were not preprocessed. This patch
adds the #include syntax instead. Evaluating this and preprocessing the files
now happens in a single step, done by the C preprocessor.

Add Linux DTS for FVP with threaded CPUs
...
In contrast with the non-multi-threading DTS, this enumerates MPIDR
values shifted by one affinity level to the left. The newly added DTS
reflects CPUs with a single thread in them.
Since both DTS files are the same apart from MPIDR contents, the common
bits have been moved to a separate file that's then included from the
top-level DTS files. The multi-threading version only updates the MPIDR
contents.

Device tree changes to boot FreeBSD on FVPs
...
FreeBSD does not understand #interrupt-map in a device tree. This prevents the
GIC from being set up correctly. This patch removes the #interrupt-map in the
device trees for the Base and Foundation FVPs. This enables correct boot of
FreeBSD on these platforms.
These changes have been tested with FreeBSD and an Ubuntu cloud image
(ubuntu-16.04-server-cloudimg-arm64-uefi1.img) to ensure compatibility with
Linux.

Fix GICv3 DT to include psci system off/reset
...
The `fvp-base-gicv3-psci` and `fvp-foundation-gicv3-psci` device tree source
files did not have psci node entries for `system off` and `system reset`.
Also the DTS files included `rtsm_ve-motherboard-no_psci.dtsi` instead of
`rtsm_ve-motherboard.dtsi`. As a result, the Linux kernel failed to invoke
the PSCI_SYSTEM_OFF/RESET API when being shutdown/reset. This patch corrects
this problem and also updates the corresponding DTB files.
This patch also removes `rtsm_ve-motherboard-no_psci.dtsi` and
`fvp-foundation-motherboard-no_psci.dtsi` files as they are no longer used.

Add cache topology info to FVP DTBs
...
From version 4.0 onwards, the ARM64 Linux kernel expects the device
tree to indicate the cache hierarchy. Failing to provide this
information results in the following warning message to be printed by
the kernel:
`Unable to detect cache hierarchy from DT for CPU x`
All the FVP device trees provided in the TF source tree have been
modified to add this information.
Fixes ARM-software/tf-issues#325

FVP: update device tree idle state entries
...
Device tree idle state bindings changed in kernel v3.18. This patch
updates the FVP DT files to use PSCI suspend as idle state.
The patch also updates the 'compatible' property in the PSCI node
and the 'entry-method' property in the idle-states node in the FVP
Foundation GICv2-legacy device tree.

Increment the PSCI VERSION to 1.0
...
This patch:
* Bumps the PSCI VERSION to 1.0. This means that
the PSCI_VERSION API will now return the value 0x00010000
to indicate the version as 1.0. The firmware remains
compatible with PSCI v0.2 clients.
* The firmware design guide is updated to document the
APIs supported by the Trusted Firmware generic code.
* The FVP Device Tree Sources (dts) and Blobs(dtb) are also
updated to add "psci-1.0" and "psci-0.2" to the list of
compatible PSCI versions.

FVP: Update device trees to match cpuidle driver

Add support for PSCI SYSTEM_OFF and SYSTEM_RESET APIs
...
This patch adds support for SYSTEM_OFF and SYSTEM_RESET PSCI
operations. A platform should export handlers to complete the
requested operation. The FVP port exports fvp_system_off() and
fvp_system_reset() as an example.
If the SPD provides a power management hook for system off and
system reset, then the SPD is notified about the corresponding
operation so it can do some bookkeeping. The TSPD exports
tspd_system_off() and tspd_system_reset() for that purpose.
Versatile Express shutdown and reset methods have been removed
from the FDT as new PSCI sys_poweroff and sys_reset services
have been added. For those kernels that do not support yet these
PSCI services (i.e. GICv3 kernel), the original dtsi files have
been renamed to *-no_psci.dtsi.

Reserve some DDR DRAM for secure use on FVP platforms
...
TZC-400 is configured to set the last 16MB of DRAM1 as secure memory and
the rest of DRAM as non-secure. Non-secure software must not attempt to
access the 16MB secure area.
Device tree files (sources and binaries) have been updated to match this
configuration, removing that memory from the Linux physical memory map.
To use UEFI and Linux with this patch, the latest version of UEFI and
the updated device tree files are required. Check the user guide in the
documentation for more details.
Replaced magic numbers with #define for memory region definition in the
platform security initialization function.

Enable secure memory support for FVPs
...
- Use the TrustZone controller on Base FVP to program DRAM access
permissions. By default no access to DRAM is allowed if
'secure memory' is enabled on the Base FVP.
- The Foundation FVP does not have a TrustZone controller but instead
has fixed access permissions.
- Update FDTs for Linux to use timers at the correct security level.
- Starting the FVPs with 'secure memory' disabled is also supported.
Limitations:
Virtio currently uses a reserved NSAID. This will be corrected in
future FVP releases.
