But I noticed that this patch breaks booting on my AXP board. I then remembered another issue I has with timer functions in SPL on MVEBU (A38x). The timer functionality is not enabled at all at this early boot time. I'll send another patch shortly. Please give it a try and let me know if this works. And if you still need this delay increasing patch here. Thank, Stefan
