From b78375a806ed04eb22b963255cfdef8df702de47 Mon Sep 17 00:00:00 2001 From: "Rajashekhara, Sudhakar" Date: Thu, 7 Jun 2012 00:27:44 +0000 Subject: [PATCH] da850/omap-l138: Enable auto negotiation in RMII mode On DA850/OMAP-L138 it was observed that in RMII mode, auto negotiation was not performed. This patch enables auto negotiation in RMII mode. Without this patch, EMAC initialization takes more time and sometimes tftp fails in RMII mode.
