[U-Boot] [PATCH 0/4] Add Cadence GEM support to macb Ethernet driver

The Cadence GEM Ethernet MAC is based on the MACB Ethernet controller but has a few small changes with regards to register and bitfield placement.

This patch set implements the changes required in order for the macb driver to support Cadence GEM as well.

These changes have been tested on a Picochip picoXcell based development platform.

Dave Aldridge (4): macb: initial support for Cadence GEM macb: support higher rate GEM MDIO clock divisors macb: support DMA bus widths > 32 bits macb: allow GEM to have configurable receive buffer size
