768  * <1> Firstly, we should know what's the GPMI-clock means.
769  *     The GPMI-clock is the internal clock in the gpmi nand controller.
770  *     If you set 100MHz to gpmi nand controller, the GPMI-clock's period
771  *     is 10ns. Mark the GPMI-clock's period as GPMI-clock-period.
774  *     The frequency on the nand chip pins is derived from the GPMI-clock.
780  *         G  : the GPMI clock, such as 100MHz.
786  *     The GPMI implements a feedback read strobe to sample the read data.
820  *                   tRP = (GPMI-clock-period) * DATA_SETUP
822  *  4.2) From the aspect of the GPMI nand controller:
826  *            if (GPMI-clock-period > DLL_THRETHOLD)
827  *                   RP = GPMI-clock-period / 2;
829  *                   RP = GPMI-clock-period;
831  *            Set the HW_GPMI_CTRL1:HALF_PERIOD if GPMI-clock-period
963 	/* Wait 64 clock cycles before using the GPMI after enabling the DLL */
986 	/* Only MX28/MX6 GPMI controller can reach EDO timings */
1819  * The tricky part in the GPMI/BCH controller is that it stores ECC bits
1826  * of the layout used by the GPMI controller.
1904  * The tricky part in the GPMI/BCH controller is that it stores ECC bits
1911  * of the layout used by the GPMI controller.
