Changes for v2:
        - MAINTAINERS file updated
        - CONFIG_MACH_TYPE added
        - hw_revision routine
Changes for v3:
        - Entry to MAINTAINERS file added to preserve an alphabethical
          order
        - Redefinition of MACH_TYPE removed at exynos4_nuri.h
        - Code cleanup (dead spaces removed)
Changes for v4:
        - get_ram_size() check added to dram_init()
        - Use of MACH_TYPE_NURI defined at ./arch/arm/include/asm/mach-types.h
          instead of a hard coded value
        - Comments correction
