From cdaed5dc31f4023610f180fe158ec8c6f5e855a3 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 9 Nov 2009 14:13:43 +0100 Subject: [PATCH] ppc4xx: Switch to I2C bus numer 0 for chip_config command All currently available 4xx derivats have the I2C bootstrap EEPROM located on I2C bus number 0. This patch now first sets this bus number, so that the chip_config command also works for board with multiple I2C busses, like Katmai.
