commit: https://git.buildroot.net/buildroot/commit/?id=bd64fdb32c6ebbc050ed7c5fcb34f51ff66ab4b8
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next
This package generates embedded Linux based OS userland client
applications and OP-TEE OS trusted applications all embedded in the
file system. These applications shows how to use the APIs OP-TEE OS is
based on, both in the non secure and secure worlds.
Package is added next to the OP-TEE client package in the BR package
configuration.
This change references in Buildroot the today's latest OP-TEE revision
release tagged 3.4.0 with an added patch to fix an issue reported by
recent GCC toolchains.

[Thomas:
- drop version selection
- propagate !BR2_STATIC_LIBS dependency of optee-client
- make sure BR2_TARGET_OPTEE_OS_SDK is selected
- use a patch generated by git format-patch
- simplify the construct to build the examples]

+ Enable the OP-TEE examples package that brings examples of
+ implementation of OP-TEE non-secure client applications and
+ secure trusted applications. OP-TEE examples is a
+ component delivered by the OP-TEE project.
+
+ Trusted application binary files are installed in the target
+ directory /lib/optee_armtz as other trusted applications.
+ At runtime OP-TEE OS can load trusted applications from this
+ non-secure filesystem/directory into the secure world for
+ execution.
