When the CMA buffer is allocated, it is too early to know whether devices will require ZONE_DMA memory. This patch limits the CMA buffer to (DMA_BIT_MASK(32) + 1) if CONFIG_ZONE_DMA is enabled. In addition, it computes the dma_to_phys(DMA_BIT_MASK(32)) before the increment (no current functional change). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |
