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 generally want to keep this value at or above 4k
- (0x1000) as this will allow the kernel to capture NULL pointer
- references.
