The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui ports present on the Cavium OCTEON family of SOCs. These SOCs are multi-core mips64 processors with existing support over in arch/mips. The driver files can be categorized into three basic groups: 1) Register definitions, these are named cvmx-*-defs.h 2) Main driver code, these have names that don't start cvmx-. 3) Interface specific functions and other utility code, names starting with cvmx- Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
