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

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.

Enable this option if you want U-Boot to hand over the Yamon-style

Enable this option if you want U-Boot to hand over a flattened

Select this (or let it be auto-selected by not defining any cache
sizes) in order to allow U-Boot to automatically detect the sizes
of caches at runtime. This has a small cost in code size & runtime
so if you know the cache configuration for your system at compile
time it would be beneficial to configure it.
