The 25ns was calculated based on the addition of trp and trhoh from the Micron MT29F8G08 datasheet. Based on the timing diagram for a "Read Status" cycle I thought this would be the minimum cycle time needed to read the chip's status. Other chips (ST, Samsung) I glanced at had > 25 ns read status times as well.
I had tried using get_timer() (I believe nand_wait() would have been perfect to use), but that didn't work due to interrupts being disabled when NAND is probed. I didn't consider using get_ticks()... That seems much better. Is get_ticks() available for all platforms when NAND is initialized?
get_ticks() not a public interface. It should not be used in any common code.
Please use get_timer().
Best regards,
