Well, this is obviously nowhere needed for U-Boot operation, and you also don't need this in U-Boot to boot your OS. See bullet # 2 at http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#2_Keep_it_Fast : We don't initialize things in U-Boot, that are not needed here, unless there is a very good reason for it. In your case, such initialization should be done in the OS device driver. Leave it out of U-Boot.
