[PATCH 0/6] firmware: arm_scmi: add OP-TEE transport support

[Ahmad Fatoum]

STM32MP15 in trusted mode and STM32MP13 by default use OP-TEE as secure
monitor and some resets, clocks and voltage regulators are off-limits
to the normal world.

This series syncs barebox SCMI support with v6.6 and adds OP-TEE as
transport alongside SMCCC. This series has been tested on:

  - STM32MP15 + OP-TEE + OP-TEE shm
  - STM32MP13 + OP-TEE + OP-TEE shm
  - STM32MP15 + OP-TEE + CFG_STM32MP1_SCMI_SIP
  - STM32MP15 + TF-A as SCMI provider (no OP-TEE)

This series depends on the OP-TEE infrastructure added in
