Add platform hooks for boot redundancy support

Change the default option of ARM_TSP_RAM_LOCATION and Enlarge the BL2 size on ARM platforms

qemu/optee: load OP-TEE pageable part 2MB above OP-TEE image

qemu: fix holding pen mailbox sequence

OP-TEE dedicates the end of the Qemu secure DRAM as specific out-of-TEE
secure RAM. To support this configuration the trusted firmware should
not load OP-TEE resources in this area.

To overcome the issue, OP-TEE pageable image is now loaded 2MByte above
the secure RAM base address.

qemu: Add support for Trusted Board Boot

This patch adds support for TBB to qemu. An RSA ROT keypair is generated at
build time and is included into BL1/BL2. The key and content certificates
are read over semihosting.

For Trusted Board Boot, BL2 needs more space to support the ECDSA
and ECDSA+RSA algorithms.

On Arm standard platforms, it runs out of SRAM space when TBB is
enabled, so the TSP default location is changed to dram when TBB
is enabled.

These hooks are intended to allow one platform to try load
images from alternative places. There is a hook to initialize
the sequence of boot locations and a hook to pass to the next
sequence.

Before this change, plat_secondary_cold_boot_setup reads wake up mailbox
as a byte array but through 64bit accesses on unaligned 64bit addresses.
In the other hand qemu_pwr_domain_on wakes secondary cores by writing
into a 64bit array.

This change forces the 64bit mailbox format as PLAT_QEMU_HOLD_ENTRY_SIZE
explicitly specifies it.

uniphier: fix section of  ROTPK hash

Update Foundation, AEM and Cortex Models versions

Fix use of MSR (immediate)

Trusted Firmware has been tested as part of its CI system against Cortex
and Foundation models in the 11.1 Model release available on
developer.arm.com. Trusted Firmware has also been tested against the
v8.7 AEM model.  This patch updates the user guide documentation to
reflect the version of the Foundation, AEM and Cortex Models that
Trusted Firmware has been tested against.

Init and save / restore of PMCR_EL0 / PMCR

Update PSCI to v1.1

Updates are required to enable the fiptool utility to be built on a
Windows platform.  This change modifies the source files to enable
building with Visual Studio (detected via preprocessor settings).
The primary changes are:
  1.  Provide an implementation of the getopt_long function.  This does
      not exist in the Visual Studio CRT libraries because Windows
      commands normally use '/' not '-' as an option indicator.
  2.  Redirect some function names to match those supported by the
      Visual Studio libraries (when building with Visual Studio).
  2.  Modify a structure name (stat) to match that provided
      by the Visual Studio libraries (_stat).

Note - this change does not provide makefile updates.  It only modifies
       the sources to enable the fiptool to be built from a Visual
       Studio project.  In normal use the presence of FIPTOOL.EXE is
       enough to satisfy the make requirements.  A makefile change may
       be derived from the Visual Studio command line information at
       some point in the future.

This patch introduces a new API in the translation tables library
(v2), that allows to change the memory attributes of a memory
region. It may be used to change its execution permissions and
data access permissions.

As a prerequisite, the memory must be already mapped. Moreover, it
must be mapped at the finest granularity (currently 4 KB).

Previously, in AArch32, `IMAGE_XLAT_DEFAULT_REGIME` wasn't defined. The
translation regime is only used in the AArch64 port of the translation
tables library v2, so this is not a problem for now, but future patches
will use it.

`IMAGE_EL` isn't used in AArch32, so it isn't needed to define it.

The GIC driver initialization currently allows an array of interrupts to
be configured as secure. Future use cases would require more interrupt
configuration other than just security, such as priority.

This patch introduces a new interrupt property array as part of both
GICv2 and GICv3 driver data. The platform can populate the array with
interrupt numbers and respective properties. The corresponding driver
initialization iterates through the array, and applies interrupt
configuration as required.

This capability, and the current way of supplying array (or arrays, in
case of GICv3) of secure interrupts, are however mutually exclusive.
Henceforth, the platform should supply either:

  - A list of interrupts to be mapped as secure (the current way).
    Platforms that do this will continue working as they were. With this
    patch, this scheme is deprecated.

  - A list of interrupt properties (properties include interrupt group).
    Individual interrupt properties are specified via. descriptors of
    type 'interrupt_prop_desc_t', which can be populated with the macro
    INTR_PROP_DESC().

A run time assert checks that the platform doesn't specify both.

Henceforth the old scheme of providing list of secure interrupts is
deprecated. When built with ERROR_DEPRECATED=1, GIC drivers will require
that the interrupt properties are supplied instead of an array of secure
interrupts.

Add a section to firmware design about configuring secure interrupts.
