![]() Currently if a DMA buffer straddles a buffer alignment boundary (512KiB) then the DMA engine will pause and generate a DMA interrupt. Since the DMA interrupt is not enabled it will hang the MMC driver. This patch adds support for restarting the DMA transfer. The SYSTEM_ADDRESS register contains the next address that would have been read/written when a boundary is hit. So we can read that and write it back. The write triggers the resumption of the transfer.
