On these boards NAND ready pin status is avilable over GPMC_WAIT0 pin. For NAND we don't use GPMC wait pin monitoring but get the NAND Ready/Busy# status using GPIOlib. GPMC driver provides the WAIT0 pin status over GPIOlib. Read speed increases from 13212 KiB/ to 15753 KiB/s and write speed was unchanged at 4404 KiB/s. Measured using mtd_speedtest.ko on omap3-beagle-c4.
