Maybe better count up to 2 in __udelay() above which makes I completely agree somehow since the time is not even constant and depends on the PLL settings just done before. I suggest the following: Removing the "* 3" fancy thingy in the function's loop, calling the function with 3000 instead of 1000, changing comment to "needed on some Beaglebone Black for warm start after reset". That would be as simple as possible.
