I am not sure if this is the right place to ask this question since this may be a U-Boot question. I am trying to understand how the source for the timer clock is selected on this processor. Figure 4-3 tries to explain this but I am unable to find code in U-Boot that actually sets either BRG1 or one of the GPIO pins to act as inputs for the timer clock generation. Can someone point me to the right place in the code where this is done? I think I know how to do it but I fail to understand where this is being actually done. All I see is the settings of PISCR and TMCNT registers in cpu initialization code. Thanks for your help in advance.
