How can I quickly pipe out bytes to an 8-bit bus on the iMX6?

I would like to configure an FPGA from and iMX6 using a configuration stored in SDRAM.  To do this I need to write 8bit data to a bus and strobe a 100MHz clk signal as I go.  Is there a peripheral that could help me ship out 8-bit data to an external bus, preferably using DMA?  I assume that the EIM is my best bet, but I am already using the EIM with said FPGA for another interface and would like to avoid the complexity. I can still use EMI, but it seems risky. I have looked through the data sheet but thought I would ask here in case there is a clever way to do it that I am missing.  Any ideas?

You may try using i.MX6 IPU display interface in asynchronous mode (system-80 interface), which is similar

to the EIM.
