fsldma: snooping is not enabled for last entry in descriptor chain On the 83xx controller, snooping is necessary for the DMA controller to ensure cache coherence with the CPU when transferring to/from RAM. The last descriptor in a chain will always have the End-of-Chain interrupt bit set, so we can set the snoop bit while adding the End-of-Chain interrupt bit. Signed-off-by: Ira W.
