[PATCH 1/4] sandbox: set DMA_ALIGNMENT instead of defining dma_alloc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


<dma.h> will take care to define dma_alloc with DMA_ALIGNMENT as
alignment. As 32 is the default and we for some reason, use 64 for
sandbox, define DMA_ALIGNMENT and drop the now duplicate code.
