	  If you don't have a boot loader capable of passing a command line string

	  This option allows you to set the load address of the kernel.
	  This can be useful if you are on a board which has a small amount
	  of memory or you wish to reserve some memory at the beginning of
	  the address space.

	  Note that you need to keep this value above 4k (0x1000) as this
	  memory region is used to capture NULL pointer references as well
	  as some core kernel functions.
