	We add config fragment support for some platform the name like: foo.config.
	There is BASE_DEFCONFIG configure to indicate the base defconfig of it.

	Usage example:
		./make.sh rv1109

		It equals: make rv1126_defconfig rv1109.config && make.


All rv1126 & rv1109 defconfigs

			It provides a template to generate <u-boot.bin> with small size for eMMC board with
			some basic features, developer is easy to enable/disable more features base on it.

			If developer wants to get a even smaller u-boot.bin, try to disable the following
			configurations accordding to board requirement.

				# CONFIG_PHY_ROCKCHIP_NANENG_USB2 is not set

				- No USB is available that U-Boot fallbacks to bootrom download mode with Menu key.
				- Recovery key is always used to enter recovery boot mode.

			[*] Remove Command-interface(33KB):
				# CONFIG_CMDLINE is not set
				CONFIG_U_BOOT_CMD_ALWAYS=y

				- Only the command that with U_BOOT_CMD_ALWAYS() delcared is available.
