From ba37aa03287c5483c61c0a3e320c8888bee0143a Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 19 Aug 2008 15:41:18 -0500 Subject: [PATCH] fdt: rework fdt_fixup_ethernet() to use env instead of bd_t Move to using the environment variables 'ethaddr', 'eth1addr', etc.. instead of bd->bi_enetaddr, bi_enet1addr, etc. This makes the code a bit more flexible to the number of ethernet interfaces.
