Hi,
I'm looking at the wic file for STM32MP13 and see two metadata partitions for ATF firmware update. I'm wondering how are these partitions secured from access / modifications from non-trusted world? Since write (and optionally read) operation should only be performed from secure world what is the mechanism that prevents doing this from non secure world? Is there any? If so, how is this configured? I'm also curious whether the same mechanism applies to STM32MP2
