Subject: 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.

From 9ca880a250870a7d55754291b5591d2b5fe89b54 Mon Sep 17 00:00:00 2001
From: Timur Tabi <timur@freescale.com>
Date: Tue, 31 Oct 2006 21:23:16 -0600
Subject: mpc83xx: Fix dual I2C support for the MPC8349ITX, MPC8349EMDS,
 TQM834x, and MPC8360EMDS

This patch also adds an improved I2C set_speed(), which handles all clock
frequencies.

Subject: mpc83xx: add OF_FLAT_TREE bits to 83xx boards

add ft_pci_setup, OF_CPU, OF_SOC, OF_TBCLK, and
STDOUT_PATH configuration bits to mpc8349emds,
mpc8349itx, and mpc8360emds board code.

redo environment to use bootm with the fdtaddr
for booting ARCH=powerpc kernels by default,
and provide default fdtaddr values.

Subject: mpc83xx: Replace CFG_IMMRBAR with CFG_IMMR

Replace all instances of CFG_IMMRBAR with CFG_IMMR, so that the 83xx
tree matches the other 8xxx trees.

Subject: mpc83xx: Update 83xx to use fsl_i2c.c

Update the 83xx tree to use I2C support in drivers/fsl_i2c.c.  Delete
cpu/mpc83xx/i2c.c, include/asm-ppc/i2c.h, and all references to those files.
Added multiple I2C bus support to fsl_i2c.c.
