The GPMC binding is obviously very confusing as the values are all over the place. People seem to confuse the GPMC partition size for the chip select, and the device IO size within the GPMC partition easily. The ranges entry contains the GPMC partition size. And the reg entry contains the size of the IO registers of the device connected to the GPMC. Let's fix the issue according to the following table: Device GPMC partition size Device IO size connected in the ranges entry in the reg entry NAND 0x01000000 (16MB) 4 16550 0x01000000 (16MB) 8 smc91x 0x01000000 (16MB) 0xf smc911x 0x01000000 (16MB) 0xff OneNAND 0x01000000 (16MB) 0x20000 (128KB) 16MB NOR 0x01000000 (16MB) 0x01000000 (16MB) 32MB NOR 0x02000000 (32MB) 0x02000000 (32MB) 64MB NOR 0x04000000 (64MB) 0x04000000 (64MB) 128MB NOR 0x08000000 (128MB) 0x08000000 (128MB) 256MB NOR 0x10000000 (256MB) 0x10000000 (256MB) Let's also add comments to the fixed entries while at it.
