This series adds commands for listing the supported partition tables,
listing supported filesystems and expands Driver Model listing commands.
The existing "dm drivers" command, which lists the DM drivers and their
compatibility strings, segmentation faulted on drivers for which of_match
was unpopulated (which appears to not be uncommon). This was fixed, and
the command was renamed "dm compat", and a new more extensive "dm drivers"
command was added, which list all DM drivers and for each, their uclass
id, uclass driver and the device names for active driver instances. The
purpose is show available drivers, but also to highlight unused drivers
or drivers with uclass ids without uclass drivers, etc.
The following commands were added:
-"part types", lists partition tables supported
-"fstypes", lists filesystem types supported
-"dm compat", lists drivers and their compatibility strings (equivalent
to existing "dm drivers" command)
-"dm drivers", lists all DM drivers, and for each their uclass id,
uclass driver and the device names for active driver instances.
-"dm static", lists all DM drivers which use static platform data
(instead of the device tree).
These patches were tested in the Sandbox and on the Wandboard
i.MX6Quad Board rev B1.
