of the address space downwards, and then returning the lowest mapped device address from initarm_lastaddr(). This adds over 500MB of kva space compared to the old way of hardcoding the end address as 0xE0000000. Also, pre-map most of the SoC's common memory-mapped devices using 1MB section mappings so that all device access uses just a few TLB entries. Graphics devices aren't mapped this way yet, but probably should be. To provide this new functionality without pasting identical code into multiple imxNN_machdep.c files, rework the imx machdep code so that things common to the whole family of SoCs are in a new imx_machdep.c file. The rewritten imxNN_machdep.c files contain just things specific to an individual SoC.
