sandbox: Add SDL library for LCD, keyboard, audio
SDL (Simple DirectMedia Layer - see is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits. Tested-by: Che-Liang Chiou <> Signed-off-by: Simon Glass <>
