From 2f3b6ef2fe4609c90976ba6aeffd836c6ccb2703 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Tue, 29 Sep 2009 10:22:45 -0400 Subject: [PATCH] TI: OMAP3: Overo Tobi ethernet support Add setup for ethernet on Tobi, allowing kernel/ramdisk to be loaded over tftp. This also refactors the smc911x driver to allow for detecting when the chip is missing. I.e. the detect_chip() function is called earlier and will abort gracefully when the Chip ID read returns all 1's.
