Probably the GPMC driver should go into a slightly different place than SDRC/EMIF. GPMC is actually a general-purpose parallel bus driver. It's used to interface Ethernet controllers, UARTs, FPGAs, NAND/NOR flash, SRAM, etc. It cannot be used to control DRAM, at least not without a separate DRAM controller chip. SDRC/EMIF are both DRAM controllers. That's all they do. They can't be used to control anything else. They implement DRAM refresh, etc. So perhaps something like drivers/memory/dram/ for the SDRAM controllers, and maybe drivers/memory/ for the GPMC? - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
