From: Matthew Gerlach <matthew.gerlach@intel.com>
This patchset enhances the definition of the Device Feature Header (DFH) used by
the Device Feature List (DFL) bus and then uses the new enhancements in a uart
driver.
Patch 1 updates the DFL documentation to provide the motivation behind the
enhancements to the definition of the DFH.
Patch 2 adds the definitions for DFHv1.
Patch 3 adds basic support DFHv1. It provides a generic mechanism for
describing MSIX interrupts used by a particular feature instance, and
it gets the location and size of the feature's register set from DFHv1.
Patch 4 adds a DFL uart driver that makes use of the new features of DFHv1.
