    crypto: ccp - Log when resetting PSP SEV state · a77aba31
    Peter Gonda authored
    Currently when the PSP returns a SECURE_DATA_INVALID error on INIT or
    INIT_EX the driver retries the command once which should reset the PSP's
    state SEV related state, meaning the PSP will regenerate its keying
    material. This is logged with a dbg log but given this will change
    system state this should be logged at a higher priority and with more
    information.
