BBM as in NAND Bad Block Management ?

As mentioned elsewhere for other vendor protocol implementations,
please provide as much documentation on these extensions as possible.
Please use the SCMI spec as the reference to provide documentation
as I expected it to be versioned and all these needs to be documented
for maintenance of upstream support.

Also explain briefly why this needs to be vendor extension even if it is
obvious. I prefer that way.
