From 2ad6b513b31070bd0c003792ed1c3e7f5d740357 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 31 Oct 2006 18:44:42 -0600 Subject: [PATCH] mpc83xx: Add support for the MPC8349E-mITX PREREQUISITE PATCHES: * This patch can only be applied after the following patches have been applied: 1) DNX#2006090742000024 "Add support for multiple I2C buses" 2) DNX#2006090742000033 "Multi-bus I2C implementation of MPC834x" 3) DNX#2006091242000041 "Additional MPC8349 support for multibus i2c" 4) DNX#2006091242000078 "Add support for variable flash memory sizes on 83xx systems" 5) DNX#2006091242000069 "Add support for Errata DDR6 on MPC 834x systems" CHANGELOG: * Add support for the Freescale MPC8349E-mITX reference design platform. The second TSEC (Vitesse 7385 switch) is not supported at this time.
