This had a tendency to happen with FDTs passed by loader, though could for other reasons as well, and would result in the kernel slowly cannibalizing itself for other purposes, eventually resulting in a crash. A similar fix is needed for mmu_oea.c and should probably just be rolled at that point into some generic code in platform.c for taking a mem_region list and removing chunks.
