[U-Boot] OMAP GPMC Controller U-Boot Class Type

I was curious to know if there is a recommendation for for what class should be used for the OMAP3's general purpose memory controller. It it a bus that is memory addressed with chip selects for various parts and has a variety of registers setup to determine the timings for the communication. Several OMAP3 devices use this bus for the NAND and NOR addressing as well as Ethernet.

I'm considering adding some code to read the timings from the device tree to change the GPMC bus timings to match. The U-Boot defaults work, but I think they are a bit conservative, and I'd like to optimize the performance.

Thanks,
