U-Boot CPU clock slower than it is in OS?

[Kyle Woolsey]

I’m doing some development on an AM335x ARM CPU and want to run
applications in the U-Boot command prompt. My problem: the code is much
slower in U-Boot than it is in Linux. I was wondering if U-Boot is able to
set clock settings and if there's a way that I can tweak them to improve
performance of programs that run from the U-Boot command prompt.
