From 3207d8fc9cc8fcc91d0dcc02890c7aaff48a6a27 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 5 Dec 2014 20:56:46 -0700 Subject: [PATCH] ARM: rpi: only set usbethaddr on relevant systems Model A and CM RPis don't have an on-board USB Ethernet device. Hence, there's no point setting $usbethaddr based on the device fuses. Use the model detection code to gate this. Note that the fuses are actually programmed even on those devices though.
