+         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.

+         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.

+         device tree to the kernel.
+
+         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.
