This is needed to support Freescale-supplied userspaces.
At the moment, both the IPU and VPU libraries provided by Freescale in the "imx-lib" package contain routines which scrape the system revision from /proc/cpuinfo. In the VPU library, this information is used to load the proper firmware, allowing a single binary to be used across various i.MX processors.
V3 removes the conditional surrounding get_board_rev() as requested by Marek.
