+    AVR32: Build position-independent u-boot

+    Add -fPIC -mno-init-got to the avr32-specific CFLAGS to make u-boot

+
+    -mno-init-got means that gcc shouldn't emit code to load the GOT

+
+    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.

+    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
+    relocates to RAM, this flag should be set.
+
+    CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the
+    system hang in exception, this flag should be set.
+
+    There is a design issue for tsi108/109 pci configure  read. When pci scan
+    the slots, if there is no pci card, the tsi108/9 will cause a machine
+    check exception for mpc7448 processor.
