Only we meet the following conditions, we can enable the DMA support for auart: (1) We enable the DMA support in the dts file, such as arch/arm/boot/dts/imx28.dtsi. (2) We enable the hardware flow control. (3) We use the mx28, not the mx23. Due to hardware bug(see errata: 2836), we can not add the DMA support to mx23.
