+          Enable FIQ support for the S3C24XX SPI driver to provide pseudo
+          DMA by using the fast-interrupt request framework, This allows
+          the driver to get DMA-like performance when there are either
+          no free DMA channels, or when doing transfers that required both
+          TX and RX data paths.
