Hi all, Memory mapping is done so that CPU can access the devices, which it cant unless.

Now the question is can we memory map a one device resource(say some iomemory) to two different memory locations? the other way of seeing at this question is, Will ioremap() gives different 'virtual addresses' when called multiple times?

I can't see any reasons for which you can't do that. The best way to find out, is to try it. thanks, Daniel.
