Cortex-Axx: Unconditionally apply CPU reset operations
In the Cortex-A35/A53/A57 CPUs library code, some of the CPU specific
reset operations are skipped if they have already been applied in a
previous invocation of the reset handler. This precaution is not
required, as all these operations can be reapplied safely.
This patch removes the unneeded test-before-set instructions in
the reset handler for these CPUs.

Disable non-temporal hint on Cortex-A53/57
The LDNP/STNP instructions as implemented on Cortex-A53 and
Cortex-A57 do not behave in a way most programmers expect, and will
most probably result in a significant speed degradation to any code
that employs them. The ARMv8-A architecture (see Document ARM DDI
0487A.h, section D3.4.3) allows cores to ignore the non-temporal hint
and treat LDNP/STNP as LDP/STP instead.
This patch introduces 2 new build flags:
A53_DISABLE_NON_TEMPORAL_HINT and A57_DISABLE_NON_TEMPORAL_HINT
to enforce this behaviour on Cortex-A53 and Cortex-A57. They are
enabled by default.
The string printed in debug builds when a specific CPU errata
workaround is compiled in but skipped at runtime has been
generalised, so that it can be reused for the non-temporal hint use
case as well.

Fix PSCI CPU ON race when setting state to ON_PENDING
When a CPU is powered down using PSCI CPU OFF API, it disables its caches
and updates its `aff_info_state` to OFF. The corresponding cache line is
invalidated by the CPU so that the update will be observed by other CPUs
running with caches enabled. There is a possibility that another CPU
which has been trying to turn ON this CPU via PSCI CPU ON API,
has already seen the update to `aff_info_state` and proceeds to update
the state to ON_PENDING prior to the cache invalidation. This may result
in the update of the state to ON_PENDING being discarded.
This patch fixes this issue by making sure that the update of `aff_info_state`
to ON_PENDING sticks by reading back the value after the cache flush and
retrying it if not updated. The patch also adds a dsbish() to
`psci_do_cpu_off()` to ensure ordering of the update to `aff_info_state`
prior to cache line invalidation.

Always build with '-pedantic'
By default ARM TF is built with the '-pedantic' compiler flag, which
helps detecting violations of the C standard. However, the mbed TLS
library and its associated authentication module in TF used to fail
building with this compiler flag. As a workaround, the mbed TLS
authentication module makefile used to set the 'DISABLE_PEDANTIC'
TF build flag.
The compiler errors flagged by '-pedantic' in the mbed TLS library
have been fixed between versions 1.3.9 and 2.2.0 and the library now
properly builds with this compiler flag.
This patch fixes the remaining compiler errors in the mbed TLS
authentication module in TF and unsets the 'DISABLE_PEDANTIC' TF
build flag. This means that TF is now always built with '-pedantic'.
In particular, this patch:
* Removes the final semi-colon in REGISTER_COT() macro.
This semi-colon was causing the following error message:
drivers/auth/tbbr/tbbr_cot.c:544:23: error: ISO C does not allow
extra ';' outside of a function [-Werror=pedantic]
This has been fixed both in the mbed TLS authentication module
as well as in the certificate generation tool. Note that the latter
code didn't need fixing since it is not built with '-pedantic' but
the change has been propagated for consistency.
Also fixed the REGISTER_KEYS() and REGISTER_EXTENSIONS() macros,

* Fixes a pointer type.

RESET_TO_BL31 configuration, even though the reset vector address
can't be programmed dynamically.
This document includes some images, which have been generated using
Dia version 0.97.2. This tool can be obtained from:

- the image files describing the different reset flow diagrams;
- the source '.dia' file;
- a script automating the generation of the images from the '.dia'

void bl1_plat_set_ep_info(unsigned int image_id,
struct entry_point_info *ep_info);
This function allows platforms to update ep_info for given
image_id.
The plat_bl1_common.c file provides default weak implementations of
all above functions, the `bl1_plat_get_image_desc()` always return
BL2 image descriptor, the `bl1_plat_get_next_image_id()` always return
BL2 image ID and `bl1_plat_set_ep_info()` is empty and just returns.
These functions gets compiled into all BL1 platforms by default.
Platform setup in BL1, using `bl1_platform_setup()`, is now done
_after_ the initialization of authentication module. This change
provides the opportunity to use authentication while doing the
platform setup in BL1.
In order to store secure/non-secure context, BL31 uses percpu_data[]
to store context pointer for each core. In case of BL1 only the
primary CPU will be active hence percpu_data[] is not required to
store the context pointer.
This patch introduce bl1_cpu_context[] and bl1_cpu_context_ptr[] to
store the context and context pointers respectively. It also also
re-defines cm_get_context() and cm_set_context() for BL1 in
bl1/bl1_context_mgmt.c.
BL1 now follows the BL31 pattern of using SP_EL0 for the C runtime
environment, to support resuming execution from a previously saved
context.
NOTE: THE `bl1_plat_set_bl2_ep_info()` PLATFORM PORTING FUNCTION IS
NO LONGER CALLED BY BL1 COMMON CODE. PLATFORMS THAT OVERRIDE
THIS FUNCTION MAY NEED TO IMPLEMENT `bl1_plat_set_ep_info()`
INSTEAD TO MAINTAIN EXISTING BEHAVIOUR.

Move context management code to common location
The upcoming Firmware Update feature needs transitioning across
Secure/Normal worlds to complete the FWU process and hence requires
context management code to perform this task.
Currently context management code is part of BL31 stage only.
This patch moves the code from (include)/bl31 to (include)/common.
Some function declarations/definitions and macros have also moved
to different files to help code sharing.

SoC security setup for CSS platforms in BL1
This patch adds support for secure setup of the SoC on CSS
platforms in BL1.
This change is required to provide memory access to normal
world images that take part in upcoming Firmware Update feature.

Remove `RUN_IMAGE` usage as opcode passed to next EL.
The primary usage of `RUN_IMAGE` SMC function id, used by BL2 is to
make a request to BL1 to execute BL31. But BL2 also uses it as
opcode to check if it is allowed to execute which is not the
intended usage of `RUN_IMAGE` SMC.
This patch removes the usage of `RUN_IMAGE` as opcode passed to
next EL to check if it is allowed to execute.
