      doc: Formatting fixes for readme.rst · 76cf653b
      Paul Beesley authored 
      

The readme.rst file in the project root is the front-page that
is displayed on Github and if viewing the TF-A repository on
git.trustedfirmware.org in the "about" view. It now contains a
small amount of stub content, and directs readers to the
ReadTheDocs documentation via trustedfirmware.org/docs/tf-a.

The Github renderer is displaying the content fine but the cgit
viewer displays some "backlink" errors because some content
substitutions were left in place (terms surrounded by pipe
symbols), e.g. |TF-A|.

This patch removes those substitutions, that are not supported
by cgit, and also updates one heading to clarify where to find
the new docs.

      doc: De-duplicate readme and license files · 8cc36aec
      Paul Beesley authored 
      

The readme.rst and license.rst files in the project root overlap
with the index.rst and license.rst files in the docs/ folder. We
need to use the latter when building the documentation, as Sphinx
requires all included files to be under a common root. However,
the files in the root are currently used by the cgit and Github
viewers.

Using symlinks in Git presents some difficulties so the best
course of action is likely to leave these files but in stub form.

The license.rst file in the root will simply tell the reader to
refer to docs/license.rst.

The readme.rst file will contain a small amount of content that
is derived from the docs/index.rst file, so that the Github main
page will have something valid to show, but it will also contain
a link to the full documentation on ReadTheDocs.

      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.

      Improvements in Readme · 0668dd71
      John Tsichritzis authored 
      

- Fix broken link to the issue tracker.
- Add contents section to make navigation easier throughout the page.
- Move the link to documentation contents near the top. Where it was
  before could be missed and documentation might seem inaccessible.

      ti: k3: Setup initial files for platform · 1841c533
      Nishanth Menon authored 
      

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.
