stm32mp: cmd_stm32key: lock of PKH OTP after fuse Lock the OTP value of key's hash after the command $> stm32key fuse <address> This operation forbids a second update of these OTP as they are ECC protected in BSEC: any update of these OTP with a different value causes a BSEC disturb error and the closed chip will be bricked.
