ARM CPUs with multi-threading implementation has more than one
Processing Element in a single physical CPU. Such an implementation will
reflect the following changes in the MPIDR register:
- The MT bit set;
- Affinity levels pertaining to cluster and CPUs occupy one level
higher than in a single-threaded implementation, and the lowest
affinity level pertains to hardware threads. MPIDR affinity level
fields essentially appear shifted to left than otherwise.
The FVP port henceforth assumes that both properties above to be
concomitant on a given FVP platform.
To accommodate for varied MPIDR formats at run time, this patch
re-implements the FVP platform-specific functions that translates MPIDR
values to a linear indices, along with required validation. The same
treatment is applied for GICv3 MPIDR hashing function as well.
An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
specifies the maximum number of threads implemented per CPU. For
backwards compatibility, its value defaults to 1.

ARM TF has been tested against Linaro Release 17.04 - the Linaro
binaries have been update and also the version of the compiler.
Linaro binaries: 17.01 --> 17.04
AArch64 & AArch32 compilers: 5.3-2015.05 (gcc 5.3) -> 6.2-2016.11 (gcc 6.2)
This patch updates the User Guide is to state that Linaro
release 17.04 is supported.
Additionally, the following fixes are made to the User Guide:
- Removed out of date reference to Linaro release 16.06.
- Updated the Juno variant coverage to include r2.

Trusted Firmware has been tested as part of its CI system against Cortex
and Foundation models in the 11.0 Model release available on
developer.arm.com. Trusted Firmware has also been tested against the v8.5
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.

Due to recent issues in the rendering of the documentation on GitHub and
some long-standing issues like the lack of automatic table of content in
Markdown, the documentation has been converted to reStructuredText.
Basic constructs looks pretty similar to Markdown.
Automatically convert GitHub markdown documentation to reStructuredText
using pandoc.
