Let's use the more appropriate udelay for the nand_spl. While we can't make use of u-boot's full udelay we can atl east use a for loop that won't get optimized away .Since we have the bus clock we can use the timebase to calculate wall time. Looked at reusing the u-boot udelay functions but it pulls in a lot of code and would require quite a bit of work to keep us within the very small space constrains we currently have Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
