      Add UBSAN support and handlers · 1f461979
      Justin Chadwell authored 
      

This patch adds support for the Undefined Behaviour sanitizer. There are
two types of support offered - minimalistic trapping support which
essentially immediately crashes on undefined behaviour and full support
with full debug messages.

The full support relies on ubsan.c which has been adapted from code used
by OPTEE.

      Romlib makefile refactoring and script rewriting · d8210dc6
      Imre Kis authored 
      

The features of the previously existing gentbl, genvar and genwrappers
scripts were reimplemented in the romlib_generator.py Python script.
This resulted in more readable and maintainable code and the script
introduces additional features that help dependency handling in
makefiles. The assembly templates were separated from the script logic
and were collected in the 'templates' directory.

The targets and their dependencies were reorganized in the makefile and
the dependency handling of included index files is possible now.
Incremental build is available in case of modifying the index files.

      doc: Generate PlantUML diagrams automatically · 7cb68807
      Paul Beesley authored 
      

Currently we have some pre-rendered versions of certain diagrams
in SVG format. These diagrams have corresponding PlantUML source
that can be rendered automatically as part of the documentation
build, removing the need for any intermediate files.

This patch adds the Sphinx "plantuml" extension, replaces
references to the pre-rendered SVG files within the documents,
and finally removes the SVG files and helper script.

New requirements for building the docs are the
"sphinxcontrib-plantuml" Python module (added to the pip
requirements.txt file) and the Graphviz package (provides the
"dot" binary) which is in the Ubuntu package repositories.

      Add support for Branch Target Identification · 9fc59639
      Alexei Fedorov authored 
      

This patch adds the functionality needed for platforms to provide
Branch Target Identification (BTI) extension, introduced to AArch64
in Armv8.5-A by adding BTI instruction used to mark valid targets
for indirect branches. The patch sets new GP bit [50] to the stage 1
Translation Table Block and Page entries to denote guarded EL3 code
pages which will cause processor to trap instructions in protected
pages trying to perform an indirect branch to any instruction other
than BTI.
BTI feature is selected by BRANCH_PROTECTION option which supersedes
the previous ENABLE_PAUTH used for Armv8.3-A Pointer Authentication
and is disabled by default. Enabling BTI requires compiler support
and was tested with GCC versions 9.0.0, 9.0.1 and 10.0.0.
The assembly macros and helpers are modified to accommodate the BTI
instruction.
This is an experimental feature.
Note. The previous ENABLE_PAUTH build option to enable PAuth in EL3
is now made as an internal flag and BRANCH_PROTECTION flag should be
used instead to enable Pointer Authentication.
Note. USE_LIBROM=1 option is currently not supported.
