From 69ad7e73dee33f8e0680825006c801ca6b4bf470 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Tue, 8 Jul 2008 21:36:40 +0400 Subject: powerpc/fsl_soc: gianfar: don't probe disabled devices Freescale ships MPC8315E-RDB boards in two variants: 1. With TSEC1 ethernet support and USB UTMI PHY; 2. Without TSEC1 support, but with USB ULPI PHY in addition. For the second case U-Boot will add status = "disabled"; property into the TSEC1 node, so Linux should not try to probe it.

Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was preventing the multiple buses from having different ids. So we only keep the low 20 bits, which have the interesting info, anyway.
