mpc83xx: Fix the incorrect dcbz operation
The 834x rev1.x silicon has one CPU5 errata.
The issue is when the data cache locked with
HID0[DLOCK], the dcbz instruction looks like no-op inst.
The right behavior of the data cache is when the data cache
Locked with HID0[DLOCK], the dcbz instruction allocates
new tags in cache.
The 834x rev3.0 and later and 8360 have not this bug inside.
So, when 834x rev3.0/8360 are working with ECC, the dcbz
instruction will corrupt the stack in cache, the processor will
checkstop reset.
However, the 834x rev1.x can work with ECC with these code,
because the sillicon has this cache bug. The dcbz will not
corrupt the stack in cache.
Really, it is the fault code running on fault sillicon.

Overview:
1. Include new 'i2c' command (based on USB implementation) using
CONFIG_I2C_CMD_TREE.
2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that
the commands to change bus number and speed are only available under the
new 'i2c' command mentioned in the first bullet.
3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus
systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form
of an array of bus-device pairs. Otherwise, it is an array of uchar.
CHANGELOG:
Added new 'i2c' master command for all I2C interaction. This is
conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for
setting I2C bus speed as well as changing the active bus if the board
has more than one (conditionally compiled with
CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses.

Tundra tsi108 on chip Ethernet controller support.
The following is a brief description of the Ethernet controller:
The Tsi108/9 Ethernet Controller connects Switch Fabric to two independent
Gigabit Ethernet ports,E0 and E1. It uses a single Management interface
to manage the two physical connection devices (PHYs). Each Ethernet port
has its own statistics monitor that tracks and reports key interface
statistics. Each port supports a 256-entry hash table for address
filtering. In addition, each port is bridged to the Switch Fabric
through a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO.
Each Ethernet port also has a pair of internal Ethernet DMA channels to
support the transmit and receive data flows. The Ethernet DMA channels
use descriptors set up in memory, the memory map of the device, and
access via the Switch Fabric. The Ethernet Controller?s DMA arbiter
handles arbitration for the Switch Fabric. The Controller also
has a register businterface for register accesses and status monitor
control.
The PMD (Physical Media Device) interface operates in MII, GMII, or TBI
modes. The MII mode is used for connecting with 10 or 100 Mbit/s PMDs.
The GMII and TBI modes are used to connect with Gigabit PMDs. Internal
data flows to and from the Ethernet Controller through the Switch Fabric.
Each Ethernet port uses its transmit and receive DMA channels to manage
data flows through buffer descriptors that are predefined by the
system (the descriptors can exist anywhere in the system memory map).
These descriptors are data structures that point to buffers filled
with data ready to transmit over Ethernet, or they point to empty
buffers ready to receive data from Ethernet.
