      stm32mp1: SCMI clock and reset service in SP_MIN · fdaaaeb4
      Etienne Carriere authored 
      

This change implements platform services for stm32mp1 to expose clock
and reset controllers over SCMI clock and reset domain protocols
in sp_min firmware.

Requests execution use a fastcall SMC context using a SiP function ID.
The setup allows the create SCMI channels by assigning a specific
SiP SMC function ID for each channel/agent identifier defined. In this
change, stm32mp1 exposes a single channel and hence expects single
agent at a time.

The input payload in copied in secure memory before the message
in passed through the SCMI server drivers. BL32/sp_min is invoked
for a single SCMI message processing and always returns with a
synchronous response message passed back to the caller agent.

This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was
previously wrongly set 4 whereas only 1 SiP SMC function ID was to
be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the
2 added SiP SMC function IDs for SCMI services.

      stm32mp1: add OP-TEE support · 1989a19c
      Yann Gautier authored 
      

Support booting OP-TEE as BL32 boot stage and secure runtime
service.

OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      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: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("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.
