The CXL.mem protocol allows a device to act as a provider of
"System RAM" and/or "Persistent Memory" that is fully coherent
as if the memory was attached to the typical CPU memory
controller.
Say 'y/m' to enable a driver that will attach to CXL.mem devices for
configuration and management primarily via the mailbox interface. See
Chapter 2.3 Type 3 CXL Device in the CXL 2.0 specification for more
details.
If unsure say 'm'.
