We're missing the board_lmb_reserve definitions that allow cpu_mp_lmb_reserve to be called; this means that Linux is free to reallocate reserved pages. Linux currently boots because we're getting lucky - the page we've reserved is high enough in memory that it isn't allocated by Linux while we still need it to be in existence.
