DTC generates warnings when unit names begin with 0, or
when a node containing a reg or range property doesn't have a unit name
in the node name. This patch fixes those cases.

DynamIQ platforms host all CPUs in a single cluster. This patch adds a
DTS and DTB for DynamicQ platforms hosting up to 8 CPUs.

The commit 8d2c4977

 changed the interrupt map in `rtsm_ve-motherboard.dtsi`
for the Linux FDT sources to be compatible for FreeBSD. But this also
introduced a regression for FVP AArch32 mode but was undetected till now
because the corresponding DTB was not updated. This patch creates a
new `rtsm_ve-motherboard-aarch32.dtsi` which reverts the change and is
now included by the AArch32 DTS files.

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.

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.

This patch adds necessary updates for building and running Trusted
Firmware for AArch32 to user-guide.md. The instructions for running
on both `FVP_Base_AEMv8A-AEMv8A` in AArch32 mode and
`FVP_Base_Cortex-A32x4` models are added. The device tree files for
AArch32 Linux kernel are also added in the `fdts` folder.

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.

This patch removes support for legacy Versatile Express memory map for the
GIC peripheral in the FVP platform. The user guide is also updated for the
same.

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.

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.

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.

This patch updates the representation of idle tables and cpu/cluster topology in
the device tree source files for the FVP to what the latest cpuidle driver in
Linux expects. The device tree binaries have also been updated.

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.

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.

- 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.

- Three FDTs are provided.
  fvp-foundation-gicv2legacy-psci:
    Use this when setting the Foundation FVP to use GICv2. In this
    mode the GIC is located at the VE location, as described in the
    VE platform memory map.
  fvp-foundation-gicv3-psci :
    Use this when setting the Foundation FVP to use GICv3. In this
    mode the GIC is located at the Base location, as described in the
    Base platform memory map.
  fvp-foundation-gicv2-psci :
    Use this when setting the Foundation FVP to use GICv3, but Linux
    is expected to use GICv2 emulation mode. In this mode the GIC is
    located at the Base location, but the GICv3 is used in GICv2
    emulation mode.
