67 Some MIPS boards can be configured for either little or big endian
68 byte order. These modes require different U-Boot images. In general there
69 is one preferred byteorder for a particular system but some systems are
70 just as commonly used in the one or the other endianness.

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

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