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

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

175 Enable this option if you want U-Boot to hand over the Yamon-style
176 environment to the kernel. Information like memory size, initrd
177 address and size will be prepared as zero-terminated key/value list.
178 The address of the environment is stored in register $a2.
181 bool "Hand over a flattened device tree to Linux kernel"
184 Enable this option if you want U-Boot to hand over a flattened

279 of caches at runtime. This has a small cost in code size & runtime
280 so if you know the cache configuration for your system at compile
281 time it would be beneficial to configure it.
