> Add OP-TEE firmware node in stm32mp15 U-Boot DTSI. This node is needed
> since commit [1] that changed U-Boot/stm32mp15 to detect OP-TEE availability
> by probing the resource instead of relying on U-Boot configuration. The software
> sequence implemented by [1] is fine but U-Boot DTS/DTSI files were not updated
> accordingly since, hence OP-TEE presence is never detected by U-Boot,
> preventing Linux kernel from using OP-TEE resources.
> 
> For consistency and to synchronize stm32mp15 DTSI files (excluding U-Boot
> specific DTSI files) with the Linux kernel ones, this change also moves the OP-
> TEE reserved memory nodes from board generic DTSI files to U-Boot specific
> board DTSI files.

Applied to u-boot-stm/master, thanks!
