STM32F4 external Sdram data to serial peripheral with dma

I have a large data buffer stored in external sdram. I'd like to send data to a serial peripheral (uart, spi or iis) directly on a dma transfer. Is it possible to do so?. Every FMC sdram example available move data from sdram to internal ram.

 

Thanks in advance.
