Changes

As you can see in Layout chapter, an expansion board is called exp-<your board name>.c and should be located in arch/arm/mach-omap2 directory, so the first step will be add a new file for your new expansion board. Following example creates a new expansion board file called exp-dummy.c (arch/arm/mach-omap2/exp-dummy.c)

#include <linux/kernel.h>

#include <linux/init.h>

void __init dummy_init(void)

{

pr_info("Initializing expansion board ... \n");

}

next, add the new file to be built
