From 7d47cee2cc57f907380f2c06f5b6c683d03e423a Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 25 Oct 2007 12:24:59 +0200 Subject: ppc4xx: Fix POST ethernet test for Haleakala The POST ethernet test needed to be changed to dynamically determine the count of ethernet devices. This code is cloned from the 4xx ethernet driver.
