We indeed already had some discussion about it with Ilias. https://lists.denx.de/pipermail/u-boot/2025-December/605924.html It seems ST deviate from the original idea behind the standard. It does not use EFI neither update capsule. TF-A is managing the selection of the boot partition (FIP image: OPTEE + bootloader) according to the FWU metadata content and is dealingwith the rollback mechanism. Linux through this tools is the update agent to select the boot image. The final goal is to have RAUC updating the boot A/B partition and switching to it calling this new tool.
