From: Peng Fan <peng.fan@nxp.com>
ZONE_DMA should not be disabled, otherwise arm64_dma_phys_limit is left uninitialized and cause swiotlb have IO TLB above 4GB which might crash some platforms
Signed-off-by: Peng Fan <peng.fan@nxp.com> ---
Not sure whether need to address code to initialize the variables or force select ZONE_DMA
