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

127 bool "Hand over legacy command line to Linux kernel"
130 Enable this option if you want U-Boot to hand over the Yamon-style
131 command line to the kernel. All bootargs will be prepared as argc/argv
132 compatible list. The argument count (argc) is stored in register $a0.
133 The address of the argument list (argv) is stored in register $a1.
135 config MIPS_BOOT_ENV_LEGACY
136 bool "Hand over legacy environment to Linux kernel"
139 Enable this option if you want U-Boot to hand over the Yamon-style
140 environment to the kernel. Information like memory size, initrd
141 address and size will be prepared as zero-terminated key/value list.
142 The address of the enviroment is stored in register $a2.
145 bool "Hand over a flattened device tree to Linux kernel"
148 Enable this option if you want U-Boot to hand over a flattened
149 device tree to the kernel. According to UHI register $a0 will be set
150 to -2 and the FDT address is stored in $a1.
