Nico Huber submitted this change.
mb/kontron/bsl6: Add new Skylake COMe module
Add Kontron/bSL6 together with Siemens/Boxer26, a baseboard for the
bSL6.
The plain bSL6 variant received little testing and only during early
development. The Boxer26 variant is actively used and fully tested.
The latest rebase was boot tested with FILO and Linux 4.19.
