I see that udelay depends on loops_per_jiffy, have you looked to see what value it is? Maybe it's garbage and some large value? Have you tried dumping the __log_buf to understand how far it got thru booting the kernel before it got hung? I assume you must be using xmd to load the image, you can also use it to dump the buffer. On another processor I have seen it get hung in the calibrate_delay call from the kernel if the interrupts or timer aren't working, but haven't ever seen that on the Powerpc.
