From: Ilya Yanok Date: Mon, 28 Nov 2011 06:37:29 +0000 (+0000) Subject: davinci_emac: move arch-independent defines to separate header X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7c587d320d110e41008bc7b658655d22485d05a6;p=u-boot.git davinci_emac: move arch-independent defines to separate header DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs also. This patch moves common defines from arch-davinci/emac_defs.h to drivers/net/davinci_emac.h DaVinci specific PHY drivers hacked to include the new header. We might want to switch to phylib in future.
