[PATCH v3 0/3] mach-snapdragon: Enable OP-TEE support

[Sumit Garg <sumit.garg@kernel.org>]

From: Sumit Garg <sumit.garg@oss.qualcomm.com>

Introduce TF-A and OP-TEE config fragment

Recently upstream TF-A/OP-TEE has started gaining support for Qcom
platforms. RB3Gen2 being the first one and more to come. U-Boot in
corresponding boot flow is packaged as a position independent executable.

So, lets add a generic U-Boot config fragment for Qcom platforms to
support TF-A/OP-TEE based TrustZone stack. Build command:

$ ./scripts/kconfig/merge_config.sh \
       configs/qcom_defconfig \
       board/qualcomm/tfa-optee.config
$ make -j`nproc` DEVICE_TREE=qcom/qcs6490-rb3gen2

Changes in v3:
- Incorporated misc. comments on patch #2.

Changes in v2:
- Add new patch #1 to export OP-TEE message UID check API
- Use OP-TEE message UID check API in order to perform the DT fixup for
  OP-TEE.
- Switch from new defconfig to a config fragment instead.
