Changes since v2: - ACPI support for 8250_dw.c - dmaengine API support for 8250 It looks like there are a few UART drivers that are more or less identical with 8250.c except they include DMA support, so if we had DMA support in 8250.c there may be no need for them. Since dmaengine is now supported on most platforms, I decided to suggest this solution. I tried to make the DMA support as simple as I could. Single transfers with single descriptors. This should be sufficient in most cases.
