iMX6 kernel page sizes

Is it possible to allocate kernel pages larger than 4KB in the linux kernel for the iMX6.  I tried turning on the HUKETLBFS Kconfig in our kernel but the unit does not boot now.  We want to create a DMA driver than can handle up to 320KB buffers from an FPGA but did not want to create multiple pages then transfer multiple buffers, one for each 4KB page.

 

Thanks in advance.
