#     powerpc: Ensure that swiotlb buffer is allocated from low memory
#     
#     Some powerpc platforms (e.g. 85xx) limit DMA-able memory way below 4G.
#     If a system has more physical memory than this limit, the swiotlb
#     buffer is not addressable because it is allocated from memblock using
#     top-down mode.
#     
#     Force memblock to bottom-up mode before calling swiotlb_init() to
#     ensure that the swiotlb buffer is DMA-able.
