A change was made to walk_memory_resource() in commit
4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a
check of find_lmb(). Add the coresponding lmb_add()
call to ps3_mm_add_memory() so that that check will
succeed.
This fixes the condition where the PS3 boots up with
only the 128 MiB of boo

Actually, we call early_init_devtree(), which populates the LMB, after
we initialize the PACA an

A change was made to walk_memory_resource() in commit
4b119e21d0c66c22e8ca03df05d9de623d0eb50f that added a
check of find_lmb(). Add the corresponding lmb_add()
call to ps3_mm_add_memory() so that that check will
succeed.
