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

139	  environment to the kernel. Information like memory size, initrd
140	  address and size will be prepared as zero-terminated key/value list.
141	  The address of the enviroment is stored in register $a2.

151	        the community agreed on the MIPS boot interface for device trees,
152	        the corresponding code will be added.
