SAMA5 ADC/Touchscreen: A little more logic
Partial implementation of a simple network routing table.
Simple routing table hooked into network build system
Add candidate net/route.h.  Not yet integrated
Add framework for Spark Core board support.  The initial commit is a clone of the Maple Mini and still needs Spark customizations
Add a user interface to manage the routing table
SAMA Touchscreen/ADC:  More progress
SAMA5 ADC and touchscreen:  Drivers are code complete and ready for test
SAMA5: Integrate touchscreen and ADC drivers into the build
SAMA5: ADC and touchscreen drivers now build without errors
SAMA5: First changes from touchscreen debug
SAMA5: Touchscreen driver now works
SAMA5:  Add LCD register definition header file
SAMA5: Completes LDCDC register definition file
Clean up queue files so that they look more like others
Clean-up routing table design.
netdev_findbyaddr() will not use a routing table if one is available.  It will also make a better decision in the case there there is no routing table but only a single network interface.
Oops here is a file that I forget to add before a recent commit
Add NSH addroute and delroute commands
Fix ordering of operations in network ioctl handling.  We need to able to distinguish an error because the command was not recognized vs. other kinds of error
