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.

General code modification for mpc7448hpc2 board support.
1. Add 7447A and 7448 processor support.
2. Add the following flags.
CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically
(such as by switch on board), this flag should be set.
CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot

CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the

Check for illegal character '=' in environment variable names.
Make sure the string passed as variable name does not contain a '='
character. This not only prevents the common error or typing
"setenv foo=bar" instead of "setenv foo bar", but (more importantly)
also closes a backdoor which allowed to delete write-protected
environment variables, for example by using "setenv ethaddr=".
Don't pass any debug options directly to the assembler
When passing the -g option to gcc, gcc automatically selects a
suitable --g<format> option to pass on to the assembler.
Thus, there's no point in forcing a specific debug option on the
assembler using the -Wa mechanism.

There's nothing fundamentally AVR32-specific in this driver, but it

* pm_get_clock_freq: Obtain the clock frequency of a given domain
* gd->console_uart: A "struct device" containing information about
register mappings, gpio resources and clocks associated with the
UART device.
