This patch reads the chipid registers directly instead of making
pm call when running at BL32. User should ensure that these registers
should always be accessed from APU in their system configuration.

TI K3 platform support

Build: add cpp build processing for dtb

rpi3: BL32 optee support

Currently TF-A doesn't initialise CNTFRQ register in CNTCTLBase
frame of the system timer. ARM ARM states that "The instance of
the register in the CNTCTLBase frame must be programmed with this
value as part of system initialization."

The psci_arch_setup() updates the CNTFRQ system register but
according to the ARM ARM, this instance of the register is
independent of the memory mapped instance. This is only an issue
for Normal world software which relies on the memory mapped
instance rather than the system register one.

This patch resolves the issue for ARM platforms.

The patch also solves a related issue on Juno, wherein
CNTBaseN.CNTFRQ can be written and does not reflect the value of
the register in CNTCTLBase frame. Hence this patch additionally
updates CNTFRQ register in the Non Secure frame of the CNTBaseN.

Because there is no BL2, BL31 must determine the entrypoint and memory
location of BL32 and BL33 on its own.

BL32_BASE and PRELOADED_BL33_BASE will be set in the corresponding board
makefile. We also allow a DTB address to be specified for cases when BL33
is a Linux image.

NOTE: It is possible to pull in this information from device tree as
well, however libfdt does not contain the required hooks to make this
happen at this point in time.

The K3 family of SoCs has multiple interconnects. The key interconnect
for high performance processors is the MSMC3 interconnect. This is
an io-coherent interconnect which exports multiple ports for each
processor cluster.

Sometimes, port 0 of the MSMC may not have an ARM cluster OR is isolated
such that the instance of ATF does not manage it. Define macros
in platform_def.h to help handle this.

Create the baseline Makefile, platform definitions file and platform
specific assembly macros file. This includes first set of constants
for the platform including cache sizes and linker format and a stub for
BL31 and the basic memory layout

K3 SoC family of processors do not use require a BL1 or BL2 binary,
since such functions are provided by an system controller on the SoC.
This lowers the burden of ATF to purely managing the local ARM cores
themselves.

The old API is deprecated and will eventually be removed.

Arm platforms now use the multi console driver for boot and runtime
consoles. However, the crash console uses the direct console API because
it doesn't need any memory access to work. This makes it more robust
during crashes.

The AArch32 port of the Trusted Firmware doesn't support this new API
yet, so it is only enabled in AArch64 builds. Because of this, the
common code must maintain compatibility with both systems. SP_MIN
doesn't have to be updated because it's only used in AArch32 builds.
The TSP is only used in AArch64, so it only needs to support the new
API without keeping support for the old one.

Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
causes the UARTs to reset (except for the one used by the TSP). This
means that they must be unregistered when suspending and re-registered
when resuming. This wasn't a problem with the old driver because it just
restarted the UART, and there were no problems associated with
registering and unregistering consoles.

The size reserved for BL2 has been increased.

This is an add-on feature that allows processing
device tree with external includes.

"-Iinclude" is also added to INCLUDES.
It allows inclusion of dt-bindings files either in dts files or drivers,
as those files will be in include/dt-bindings/.

"-i fdts" is added to the DTC command line.
As the pre-processed files are in build directory, the DT source directory
has to be explicitely included, to manages /include/ directives.
