      Update pathnames in maintainers.rst file · 54895747
      Sandrine Bailleux authored 
      

The maintainers.rst file lists files and directories that each contributor looks
after in the TF-A source tree. As files and directories move around over time,
some pathnames had become invalid. Fix them, either by updating the path if
it has just moved, or deleting it altogether if it doesn't seem to exist
anymore.

      doc: Move "About" content from index.rst to a new chapter · 8eb9490b
      Paul Beesley authored 
      

The index.rst page is now the primary landing page for the TF-A
documentation. It contains quite a lot of content these days,
including:

- The project purpose and general intro
- A list of functionality
- A list of planned functionality
- A list of supported platforms
- "Getting started" links to other documents
- Contact information for raising issues

This patch creates an "About" chapter in the table
of contents and moves some content there. In order,
the above listed content:

- Stayed where it is. This is the right place for it.
- Moved to About->Features
- Moved to About->Features (in subsection)
- Stayed where it is. Moved in a later patch.
- Was expanded in-place
- Moved to About->Contact

      doc: Reword document titles · 8aa05055
      Paul Beesley authored 
      

This patch attempts to standardise the document titles as well as
adding titles to documents that were missing one. The aim is to
remove needless references to "TF-A" or "Trusted Firmware" in the
title of every document and to make sure that the title matches
with the document content.

      doc: Move documents into subdirectories · 40d553cf
      Paul Beesley authored 
      

This change creates the following directories under docs/
in order to provide a grouping for the content:

- components
- design
- getting_started
- perf
- process

In each of these directories an index.rst file is created
and this serves as an index / landing page for each of the
groups when the pages are compiled. Proper layout of the
top-level table of contents relies on this directory/index
structure.

Without this patch it is possible to build the documents
correctly with Sphinx but the output looks messy because
there is no overall hierarchy.

      rockchip: document platform · 55617251
      Heiko Stuebner authored 
      

This adds a rockchip.rst to docs/plat documenting the general
approach to using the Rockchip ATF platforms together with the
supported bootloaders and also adds myself as maintainer after
making sure Tony Xie is ok with that.

	Update IPL and Secure Monitor Rev1.0.22

General Information:
===================

This port has been tested on the Salvator-X Soc_id r8a7795 revision
ES1.1 (uses an SPD).

Build Tested:
-------------
ATFW_OPT="LSI=H3 RCAR_DRAM_SPLIT=1 RCAR_LOSSY_ENABLE=1"
MBEDTLS_DIR=$mbedtls

$ make clean bl2 bl31 rcar PLAT=rcar ${ATFW_OPT} SPD=opteed

  Until it gets merged into OP-TEE, the port requires Renesas' Trusted
  Environment with a modification to support power management.

Overview
---------

BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
at this exception level (the Renesas' ATF reference tree [1] resets into
EL1 before entering BL2 - see its bl2.ld.S)

BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
before determining the boot reason (cold or warm).

During suspend all CPUs are switched off and the DDR is put in
backup mode (some kind of self-refresh mode). This means that BL2 is
always entered in a cold boot scenario.

Once BL2 boots, it determines the boot reason, writes it to shared
memory (BOOT_KIND_BASE) together with the BL31 parameters
(PARAMS_BASE) and jumps to BL31.

To all effects, BL31 is as if it is being entered in reset mode since
it still needs to initialize the rest of the cores; this is the reason
behind using direct shared memory access to  BOOT_KIND_BASE and
PARAMS_BASE instead of using registers to get to those locations (see
el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
case).

Depending on the boot reason BL31 initializes the rest of the cores:
in case of suspend, it uses a MBOX memory region to recover the
program counters.
