> 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
