      doc: Fix platform port inclusion · f1e0f152
      Paul Beesley authored 
      

This patch:

- Adds any leftover platform ports that were not having their
  documentation built (not in the index.rst table of contents)
- Corrects a handful of RST formatting errors that cause poor
  rendering
- Reorders the list of platforms so that they are displayed
  in alphabetical order

      rpi4: Add initial documentation file · e0dea671
      Andre Przywara authored 
      

As the Raspberry Pi4 port is now in a usable state, add the build
instructions together with some background information to the
documentation directory.
The port differs quite a bit from the Raspberry Pi 3, so we use a
separate file for that.

      doc: Render Marvell platform documents · 2966defa
      Paul Beesley authored 
      

The documentation for Marvell platforms was not included in the
rendered document output until now because, while it was mostly
valid RST format, the files were saved with a .txt extension.

This patch corrects some RST formatting errors, creates a document
tree (index page) for the Marvell documents, and adds the Marvell
subtree to the main index.

      Refactor ARMv8.3 Pointer Authentication support code · ed108b56
      Alexei Fedorov authored 
      

This patch provides the following features and makes modifications
listed below:
- Individual APIAKey key generation for each CPU.
- New key generation on every BL31 warm boot and TSP CPU On event.
- Per-CPU storage of APIAKey added in percpu_data[]
  of cpu_data structure.
- `plat_init_apiakey()` function replaced with `plat_init_apkey()`
  which returns 128-bit value and uses Generic timer physical counter
  value to increase the randomness of the generated key.
  The new function can be used for generation of all ARMv8.3-PAuth keys
- ARMv8.3-PAuth specific code placed in `lib\extensions\pauth`.
- New `pauth_init_enable_el1()` and `pauth_init_enable_el3()` functions
  generate, program and enable APIAKey_EL1 for EL1 and EL3 respectively;
  pauth_disable_el1()` and `pauth_disable_el3()` functions disable
  PAuth for EL1 and EL3 respectively;
  `pauth_load_bl31_apiakey()` loads saved per-CPU APIAKey_EL1 from
  cpu-data structure.
- Combined `save_gp_pauth_registers()` function replaces calls to
  `save_gp_registers()` and `pauth_context_save()`;
  `restore_gp_pauth_registers()` replaces `pauth_context_restore()`
  and `restore_gp_registers()` calls.
- `restore_gp_registers_eret()` function removed with corresponding
  code placed in `el3_exit()`.
- Fixed the issue when `pauth_t pauth_ctx` structure allocated space
  for 12 uint64_t PAuth registers instead of 10 by removal of macro
  CTX_PACGAKEY_END from `include/lib/el3_runtime/aarch64/context.h`
  and assigning its value to CTX_PAUTH_REGS_END.
- Use of MODE_SP_ELX and MODE_SP_EL0 macro definitions
  in `msr	spsel`  instruction instead of hard-coded values.
- Changes in documentation related to ARMv8.3-PAuth and ARMv8.5-BTI.

      Remove RSA PKCS#1 v1.5 support from cert_tool · 6a415a50
      Justin Chadwell authored 
      Support for PKCS#1 v1.5 was deprecated in SHA 1001202d and fully removed
in SHA fe199e3b

, however, cert_tool is still able to generate
certificates in that form. This patch fully removes the ability for
cert_tool to generate these certificates.

Additionally, this patch also fixes a bug where the issuing certificate
was a RSA and the issued certificate was EcDSA. In this case, the issued
certificate would be signed using PKCS#1 v1.5 instead of RSAPSS per
PKCS#1 v2.1, preventing TF-A from verifying the image signatures. Now
that PKCS#1 v1.5 support is removed, all certificates that are signed
with RSA now use the more modern padding scheme.

This patch adds documentation for the new KEY_SIZE build option that is

      Invalidate dcache build option for bl2 entry at EL3 · b90f207a
      Hadi Asyrafi authored 
      

Some of the platform (ie. Agilex) make use of CCU IPs which will only be
initialized during bl2_el3_early_platform_setup. Any operation to the
cache beforehand will crash the platform. Hence, this will provide an
option to skip the data cache invalidation upon bl2 entry at EL3

      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.
