From: Fabio Estevam Date: Tue, 20 Dec 2011 05:46:31 +0000 (+0000) Subject: net: imx: Add multi-FEC support for imx_get_mac_from_fuse X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=be252b654a018cd9f513b0f2a5da4855a209c40c;p=u-boot.git net: imx: Add multi-FEC support for imx_get_mac_from_fuse Add multi-FEC support for imx_get_mac_from_fuse by passing dev_id as a parameter. This feature is important on mx28 SoC for example that has two FEC ports.
