      doc: Add contents.rst to link to pages · 9dc5f21e
      Paul Beesley authored 
      

This is the temporary contents page that links
to all other documents (except platform ports).

This page is needed during the
trustedfirmware.org migration, before we have a
Sphinx rendering pipeline set up, because cgit
doesn't offer a good way to view rendered docs
while browsing the tree. We need to have a links
page that can be opened from the cgit 'about'
view.

      ROMLIB bug fixes · ae2e01b8
      John Tsichritzis authored 
      

Fixed the below bugs:
1) Bug related to build flag V=1: if the flag was V=0, building with
ROMLIB would fail.
2) Due to a syntax bug in genwrappers.sh, index file entries marked as
"patch" or "reserved" were ignored.
3) Added a prepending hash to constants that genwrappers is generating.
4) Due to broken dependencies, currently the inclusion functionality is
intentionally not utilised. This is why the contents of romlib/jmptbl.i
have been copied to platform specific jmptbl.i files. As a result of the
broken dependencies, when changing the index files, e.g. patching
functions, a clean build is always required. This is a known issue that
will be fixed in the future.

      Declare PAuth for Secure world as experimental · 06715f85
      Alexei Fedorov authored 
      

Declare ENABLE_PAUTH and CTX_INCLUDE_PAUTH_REGS
build options as experimental.
Pointer Authentication is enabled for Non-secure world
irrespective of the value of these build flags if the
CPU supports it.
The patch also fixes the description of fiptool 'help' command.

      Tegra: Support for scatterfile for the BL31 image · c2ad38ce
      Varun Wadekar authored 
      

This patch provides support for using the scatterfile format as
the linker script with the 'armlink' linker for Tegra platforms.

In order to enable the scatterfile usage the following changes
have been made:

* provide mapping for ld.S symbols in bl_common.h
* include bl_common.h from all the affected files
* update the makefile rules to use the scatterfile and armlink
  to compile BL31
* update pubsub.h to add sections to the scatterfile

NOTE: THIS CHANGE HAS BEEN VERIFIED WITH TEGRA PLATFORMS ONLY.

      Add support for pointer authentication · b86048c4
      Antonio Nino Diaz authored 
      

The previous commit added the infrastructure to load and save
ARMv8.3-PAuth registers during Non-secure <-> Secure world switches, but
didn't actually enable pointer authentication in the firmware.

This patch adds the functionality needed for platforms to provide
authentication keys for the firmware, and a new option (ENABLE_PAUTH) to
enable pointer authentication in the firmware itself. This option is
disabled by default, and it requires CTX_INCLUDE_PAUTH_REGS to be
enabled.

      Add ARMv8.3-PAuth registers to CPU context · 5283962e
      Antonio Nino Diaz authored 
      

ARMv8.3-PAuth adds functionality that supports address authentication of
the contents of a register before that register is used as the target of
an indirect branch, or as a load.

This feature is supported only in AArch64 state.

This feature is mandatory in ARMv8.3 implementations.

This feature adds several registers to EL1. A new option called
CTX_INCLUDE_PAUTH_REGS has been added to select if the TF needs to save
them during Non-secure <-> Secure world switches. This option must be
enabled if the hardware has the registers or the values will be leaked
during world switches.

To prevent leaks, this patch also disables pointer authentication in the
Secure world if CTX_INCLUDE_PAUTH_REGS is 0. Any attempt to use it will
be trapped in EL3.
