I would swear (and I just dug up the notes from the last time I was
looking at this) that no, CONFIG_SYS_BOOTMAPSZ is not sufficient because
it doesn't cover the ramdisk case, which is important for generic
distro, unless you also add in initrd_high=top-of-lowmem-value or know
it'll be in an always-good spot and set it to 0xffffffff.
