From: Robert Winkler robert.winkler@boundarydevices.com
Add support for Boundary Devices 7" and 10.1" 1280x800 displays with integrated FocalTech ft5x06 10-point touch controller.
Because they share the touch controller with the 1024x600 displays, auto-detection is disabled and you must explicitly set the 'panel' environment variable:
U-Boot > setenv panel LDB-WXGA U-Boot > saveenv && reset
