Hi there,
We don't have GPMI driver unfortunately. You'll have to write one from scratch. I suggest you doing the CAmkES timer tutorial[1] first, to get an idea of how to gain access of the device memory and IRQ from seL4. Then, read the i.MX7 processor reference manual[2] (chapter 9.6) to understand how GPMI controller works. You could simply modify the .camkes file in the timer tutorial to have something to start with. You could also use the U-boot driver[3] as a reference.
Regards, Siwei
