Until we eventually remove 1.2 support (if we do), the identify structure should reflect the specification as is. JavierI already started on removing the MLC bits in previous patches. These two patches continue that trend. I don't know of any implementing either multiple groups or MLC, and since it has not been implemented before, no one is going to use it. No reason to have dead code hanging around. This is similar to the NVMe device driver not having definitions for all that is in the specification until it is used in the implementation.
It's ok with me - just wanted to point out that it seems weird removing bits from the structure that describes the 1.2 identify command. Guess these can com back if someone ever needs them... Javier
