Paul Burton 20286cdff7 MIPS: Simplify CONFIG_SYS_CPU values
Rather than having the values for CONFIG_SYS_CPU depend upon each
architecture revision, have them depend upon the more general
CONFIG_CPU_MIPS32 & CONFIG_CPU_MIPS64 which in turn depend upon the
architecture revisions.

This is done in preparation for adding MIPSr6 support, which would
otherwise need to introduce new cases here.

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

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

The address of the environment is stored in register $a2.
