Dear Spencer Putt,
In message OF804207B5.958BB343-ON86257506.0064304D-86257506.00643054@mck.us.ray.com you wrote:

The current init_pll_866 makes a bad assumption for the oscillator. A board with a slower oscillator may lead to PLPRCR fields overflowing their bounds and making the board not boot. This patch should more accurately set the PLPRCR regardless of the oscillator, and will increase the probability a board will boot by doing some bounds checking.

Your patch is completely white-space corrupted, probably by your Lotus mailer.
Please retry sending after fixing your mail configuration. It is best when you use git-format-patch to create the patch and git-send-email to send it.
Best regards,
