Can we map a device address to two different memory locations?

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? Please give reply.. -- With regards, Sandeep Kumar Anantapalli,
