Intel Quark SoC integrates two 10/100 ethernet controllers which can be connected to an external RMII PHY. The MAC IP is from Designware. Enable this support with the existing U-Boot Designware MAC driver so that the ethernet port on Intel Galileo board can be used.

BTW I expect the driver model Ethernet support to land soon, and I sent a series that moves the Designware Ethernet to driver model. So by the time we come to apply this, we may want to use that. But as things stand it looks good.
