    xtensa: enable HAVE_DMA_CONTIGUOUS · 9d2ffe5c
    Max Filippov 提交于
    Enable HAVE_DMA_CONTIGUOUS, reserve contiguous memory at bootmem_init,
    use dma_alloc_from_contiguous and dma_release_from_contiguous in
    xtensa_dma_alloc/free.
    This allows for big contiguous DMA buffer allocation from designated
    area configured in the device tree.
