	  Some MIPS boards can be configured for either little or big endian

	  just as commonly used in the one or the other endianness.

	  Enable this option if you want U-Boot to hand over the Yamon-style
	  command line to the kernel. All bootargs will be prepared as argc/argv
	  compatible list. The argument count (argc) is stored in register $a0.
	  The address of the argument list (argv) is stored in register $a1.

config MIPS_BOOT_ENV_LEGACY
	bool "Hand over legacy environment to Linux kernel"
	default y
	help
	  Enable this option if you want U-Boot to hand over the Yamon-style
	  environment to the kernel. Information like memory size, initrd
	  address and size will be prepared as zero-terminated key/value list.
	  The address of the enviroment is stored in register $a2.

	  Enable this option if you want U-Boot to hand over a flattened

	  Note: the final hand over to the kernel is not yet implemented. After
	        the community agreed on the MIPS boot interface for device trees,
	        the corresponding code will be added.
