Since I recently discovered scripts/kconfig/merge_config.sh, I thought
I'd share a very convenient way of automating the variations on a
kconfig theme, just in case I'm not the last one to discover this useful
tool.

For example, I have the following in am335x_only.config:

  CONFIG_ARCH_OMAP2=n
  CONFIG_ARCH_OMAP3=n
  CONFIG_ARCH_OMAP4=n
  CONFIG_SOC_OMAP5=n
  CONFIG_SOC_AM33XX=y

Then I run:

  scripts/kconfig/merge_config.sh arch/arm/configs/omap2plus_defconfig /path/to/am335x_only.config

This gives me omap2plus_defconfig with overrides from my fragment.
