In general, imx27 does support SSI with DMA, for example MACH_IMX27_VISSTRIM_M10 does use SSI with DMA. But there are special boards like Eukrea TLV320 and phycore-ac97 that have to use FIQ instead. All of them have a imx27 chip.
Why is the decision to use FIQ board-specific? All of the hardware is inside the SoC itself. How could a board make using DMA impossible?
