the memory size and the root device (e.g., mem=8M, root=/dev/nfs).

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.
