	  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.
