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

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