71 "raw_rpmb_size_mult" is a mutliple of 128kB block.

34This is a feature of the card and not of the kernel. If the card does
35not support boot partition locking, the file will not exist. If the
36feature has been disabled on the card, the file will be read-only.

38The boot partitions can also be locked permanently, but this feature is
39not accessible through sysfs in order to avoid accidental or malicious
40bricking.
