Is this documented somewhere? Or just a value from your experiments / tests?

In general I'm fine with this patch. 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
