          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.
+         Note that you need to keep this value above 4k (0x1000) as this
