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.

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.

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.

An earlier patch added provision for the platform to provide secure
interrupt properties. ARM platforms already has a list of interrupts
that fall into different secure groups.
This patch defines macros that enumerate interrupt properties in the
same fashion, and points the driver driver data to a list of interrupt
properties rather than list of secure interrupts on ARM platforms. The
deprecated interrupt list definitions are however retained to support
legacy builds.
Configuration applied to individual interrupts remain unchanged, so no
runtime behaviour change expected.
NOTE: Platforms that use the arm/common function
plat_arm_gic_driver_init() must replace their PLAT_ARM_G1S_IRQS and
PLAT_ARM_G0_IRQS macro definitions with PLAT_ARM_G1S_IRQ_PROPS and
PLAT_ARM_G0_IRQ_PROPS macros respectively, using the provided
INTR_PROP_DESC macro.

The back end GIC driver converts and assigns the interrupt type to
suitable group.
For GICv2, a build option GICV2_G0_FOR_EL3 is introduced, which
determines to which type Group 0 interrupts maps to.
- When the build option is set 0 (the default), Group 0 interrupts are
meant for Secure EL1. This is presently the case.
- Otherwise, Group 0 interrupts are meant for EL3. This means the SPD
will have to synchronously hand over the interrupt to Secure EL1.
The query API allows the platform to query whether the platform supports
interrupts of a given type.

During system suspend, the GICv3 Distributor and Redistributor context
can be lost due to power gating of the system power domain. This means
that the GICv3 context needs to be saved prior to system suspend and
restored on wakeup. Currently the consensus is that the Firmware should
be in charge of this. See tf-issues#464 for more details.
This patch introduces helper APIs in the GICv3 driver to save and
restore the Distributor and Redistributor contexts. The GICv3 ITS
context is not considered in this patch because the specification says
that the details of ITS power management is implementation-defined.
These APIs are expected to be appropriately invoked by the platform
layer during system suspend.

Commit 11ad8f208d added supporting
multi-threaded CPUs on FVP platform, including modifications for
calculating CPU IDs. This patch imports the strong definition of the
same CPU ID calculation on FVP platform for TSP.
Without this patch, TSP on FVP was using the default CPU ID calculation,
which would end up being wrong on CPUs with multi-threading.

On ARM platforms, the maximum size of the address space is limited
to 32-bits as defined in arm_def.h. In order to access DRAM2, which
is defined beyond the 32-bit address space, the maximum address space
is increased to 36-bits in AArch64. It is possible to increase the
virtual space for AArch32, but it is more difficult and not supported
for now.
NOTE - the actual maximum memory address space is platform dependent
and is checked at run-time by querying the PARange field in the
ID_AA64MMFR0_EL1 register.

mem_protect needs some kind of non-volatile memory because it has
to remember its state across reset and power down events.
The most suitable electronic part for this feature is a NVRAM
which should be only accesible from the secure world. Juno and
FVP lack such hardware and for this reason the MEM_PROTECT
functionality is implemented with Flash EEPROM memory on both
boards, even though this memory is accesible from the non-secure
world. This is done only to show a full implementation of
these PSCI features, but an actual system shouldn't use a
non-secure NVRAM to implement it.
The EL3 runtime software will write the mem_protect flag and BL2
will read and clear the memory ranges if enabled. It is done in
BL2 because it reduces the time that TF needs access to the full
non-secure memory.
The memory layout of both boards is defined using macros which
take different values in Juno and FVP platforms. Generic platform
helpers are added that use the platform specific macros to generate
a mem_region_t that is valid for the platform.

For Trusted Board Boot, BL1 RW section and BL2 need more space to
support the ECDSA algorithm. Specifically, PLAT_ARM_MAX_BL1_RW_SIZE
is increased on ARM platforms.
And on the Juno platform:
- BL2 size, PLAT_ARM_MAX_BL2_SIZE is increased.
- SCP_BL2 is loaded into the space defined by BL31_BASE ->
BL31_RW_BASE. In order to maintain the same size space for
SCP_BL2,PLAT_ARM_MAX_BL31_SIZE is increased.

The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in
AArch64. This is inconsistent and that's why we avoid using it as per
the Coding Guidelines. This patch changes all `UL` occurrences to `U`
or `ULL` depending on the context so that the size of the constant is
clear.
This problem affected the macro `BIT(nr)`. As long as this macro is used
to fill fields of registers, that's not a problem, since all registers
are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the
macro is used to fill the fields of a 64-bit integer, it won't be able
to set the upper 32 bits in AArch32.
By changing the type of this macro to `unsigned long long` the behaviour
is always the same regardless of the architecture, as this type is
64-bit wide in both cases.
Some Tegra platform files have been modified by this patch.
