(beaglebone) duplicate entries in /proc/iomem

Hi list,

Can someone shed some light on the duplicate entries in this /proc/
iomem? How am I suppose to decode this output?

For example, AM335x technical reference manual says 0x481A_E000 is for
GPIO3. but /proc/iomem shows the following:

44e07000-44e07fff : omap_gpio.3
  44e07000-44e07fff : omap_gpio.2
    44e07000-44e07fff : omap_gpio.1
      44e07000-44e07fff : omap_gpio.0

and what is omap_hsmmc? I couldn't find any reference in the technical
reference manual.

thanks.
