As answered already in (unanswered)

switch to 12MHz will have a larger code and implementation impact
while we won't win anything compared to well tested 13MHz usage

It seems to me that you mix here OMAP1 and OMAP3 patches?

I remember about

http://lists.denx.de/pipermail/u-boot/2009-April/051271.html

which is regarding arm925/OMAP1 changes, not OMAP3 patch. I can't
remember anything similar regarding OMAP3 patch. And similar comment
for OMAP3 patch wouldn't make sense as

http://lists.denx.de/pipermail/u-boot/2009-April/051178.html

has clear info

+ * We run the counter with 13MHz, divided by 8, resulting in timer
+ * frequency of 1.625MHz. With 32bit counter register, counter
+ * overflows in ~44min
