Subject: [RFC PATCH v2 01/14] docs: cxl: Add basic documentation
Date:   Tue,  8 Dec 2020 16:24:05 -0800

This starts a new cxl directory because CXL is a new bus and it is
expected that the documentation will grow large over time. Currently
only memory devices are documented as they are all that's supported.
