Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Commit 4c0d039076 ("Rework type usage in Trusted Firmware") changed
the type usage in struct declarations, but did not touch the definition
side. Fix the type mismatch.

Software executing in the normal world and in the trusted world at
exception levels lower than EL3 will request runtime services using the
SMC instruction.
See the documentation here:
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/
rt-svc-writers-guide.md
This to be implemented as an EL3 Runtime Service in rockchip BL31
platform port, using the "SiP Service Call" range as specified in the
SMC Calling Convention.
This doesn't support any SMC yet, we will support it in later.

This patch adds to support the RK3368 and RK3399 SoCs.
RK3368/RK3399 is one of the Rockchip family SoCs, which is an
multi-cores ARM SoCs.
This patch adds support to boot the Trusted Firmware on RK3368/RK3399
SoCs, and adds support to boot secondary CPUs, enter/exit core
power states for all CPUs in the slow/fast clusters.
This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
* Support arm gicv2 & gicv3.
* Boot up multi-cores CPU.
* Add generic CPU helper functions.
* Support suspend/resume.
* Add system_off & system_reset implementation.
* Add delay timer platform implementation.
* Support the new porting interface for the PSCI implementation.

This patch adds a CoT based on the Trusted Board Boot Requirements
document*. The CoT consists of an array of authentication image
descriptors indexed by the image identifiers.
A new header file with TBBR image identifiers has been added.
Platforms that use the TBBR (i.e. ARM platforms) may reuse these
definitions as part of their platform porting.
PLATFORM PORT - IMPORTANT:
Default image IDs have been removed from the platform common
definitions file (common_def.h). As a consequence, platforms that
used those common definitons must now either include the IDs
provided by the TBBR header file or define their own IDs.
*The NVCounter authentication method has not been implemented yet.

This patch adds a tool that generates all the necessary elements
to establish the chain of trust (CoT) between the images.
The tool reads the binary images and signing keys and outputs the
corresponding certificates that will be used by the target at run
time to verify the authenticity of the images.
Note: the platform port must provide the file platform_oid.h. This
file will define the OIDs of the x509 extensions that will be added
to the certificates in order to establish the CoT.

This patch implements the TSP on Juno. It executes from on-chip Trusted
SRAM.
Also, the other bootloader images (i.e. BL1 R/W, BL2 and BL3-1) have
been moved around. The reason is, although there was enough space
overall to store the TSP in SRAM, there was no contiguous free chunk
of SRAM big enough to hold it.
This patch keeps the overall memory layout (i.e. keeping BL1 R/W at
the bottom, BL2 at the top and BL3-1 in between) but moves the base
addresses of all the bootloader images in such a way that:
- memory fragmentation is reduced enough to fit BL3-2 in;
- new base addresses are suitable for release builds as well as debug
ones;
- each image has a few extra kilobytes for future growth.
BL3-1 and BL3-2 are the images which received the biggest allocations
since they will most probably grow the most.
This patch also adds instruction synchronization barriers around the code which
handles the timer interrupt in the TSP. This ensures that the interrupt is not
acknowledged after or EOIed before it is deactivated at the peripheral.

This patch adds the initial port of the ARM Trusted Firmware on the Juno
development platform. This port does not support a BL3-2 image or any PSCI APIs
apart from PSCI_VERSION and PSCI_CPU_ON. It enables workarounds for selected
Cortex-A57 (#806969 & #813420) errata and implements the workaround for a Juno
platform errata (Defect id 831273).

Move the remaining IO storage source file (io_storage.c) from the
lib to the drivers directory. This requires that platform ports
explicitly add this file to the list of source files.
Also move the IO header files to a new sub-directory, include/io.

Update code base to remove variables from the .data section,
mainly by using const static data where possible and adding
the const specifier as required. Most changes are to the IO
subsystem, including the framework APIs. The FVP power
management code is also affected.
Delay initialization of the global static variable,
next_image_type in bl31_main.c, until it is realy needed.
Doing this moves the variable from the .data to the .bss
section.
Also review the IO interface for inconsistencies, using
uintptr_t where possible instead of void *. Remove the
io_handle and io_dev_handle typedefs, which were
unnecessary, replacing instances with uintptr_t.

Reduce the number of header files included from other header
files as much as possible without splitting the files. Use forward
declarations where possible. This allows removal of some unnecessary
"#ifndef __ASSEMBLY__" statements.
Also, review the .c and .S files for which header files really need
including and reorder the #include statements alphabetically.

Move almost all system include files to a logical sub-directory
under ./include. The only remaining system include directories
not under ./include are specific to the platform. Move the
corresponding source files to match the include directory
structure.
Also remove pm.h as it is no longer used.

The modified implementation uses the IO abstraction rather than
making direct semi-hosting calls. The semi-hosting driver is now
registered for the FVP platform during initialisation of each boot
stage where it is used. Additionally, the FVP platform includes a
straightforward implementation of 'plat_get_image_source' which
provides a generic means for the 'load_image' function to determine
how to access the image data.
