+This low level driver is a test stub that doesn't talk to any

+real hardware. It is included to allow testing of the compilation

+process.

+

+Do not use this driver as a template for new drivers. Use the

+	templates/gdispXXXXX directory for that.

+

+To use this driver:

+

+1. Add in your halconf.h:

+	a) #define HAL_USE_GDISP	TRUE

+	b) Any optional high level driver defines (see gdisp.h)

+		you want to compile test eg: GDISP_NEED_MULTITHREAD

+

+2. To your makefile add the following lines:

+	include $(CHIBIOS)/os/halext/halext.mk

+	include $(CHIBIOS)/os/halext/drivers/gdispTestStub/gdisp_lld.mk
