FWU on stm32mp25

Hello,

I have a STM32MP2 platform with A/B partitioning for TF-A, metadata and FIP.

I'm looking for a way to generate a test FIP and install it in FIP-B bank, have TF-A load it, if this FIP contains a bad signature or other error that will prevent Uboot or OPTEE containing this FIP from loading and launching, my platform reboots and TF-A reloads the functional FIP (FIP-A) and boots the platform correctly. the metadata.bin file generated by default in the TF-A recipe (meta-st-stm32mp) is installed in both partitions A and B, and both always load FIP-A!

Thank you !
