[U-Boot] [PATCH 18/28] fm/mEMAC: add mEMAC frame work
York Sun
yorksun at freescale.com
Mon Oct 8 19:44:21 CEST 2012
From: Roy Zang <tie-fei.zang at freescale.com>
The multirate ethernet media access controller (mEMAC) interfaces to
10Gbps and below Ethernet/IEEE 802.3 networks via either RGMII/RMII
interfaces or XAUI/XFI/SGMII/QSGMII using the high-speed SerDes interface.
