[PATCH 0/2] dma: pl330: Fixes for DMA memcpy

[Jon Medhurst]

This is a couple of patches I produced when trying to get dmatest to run
with the pl330 driver. The second one is actually a theoretical fix
because the FIFO on the platform I was using is too large for the tests
to hit the limit, but the datasheet says the device can lockup if all
the FIFO entries are exhausted, so it seems like a sensible precaution.
