+ Rewrite the resource management code (i.e. I/O memory, clock gating,

+ can't write to any global variables.

+
+ -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.

+
+ 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
+ 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.

+
+Quick overview where U-Boot comes into the picture:
+- OS saves device states
+- OS saves wakeup handler address to physical 0x0, puts SDRAM into
+ self-refresh and signals to QT, it should power down the board
+- / board is sleeping here /
+- someone presses SW4 (connected to QT)
+- U-Boot checks PSC2_4 pin, if QT drives it down, then we woke up,
+ so get SDRAM out of self-refresh and transfer control to OS
+ wakeup handler
+- OS restores device states

+This was tested on Linux with USB and Ethernet in use. Adding
+support for other devices is an OS issue.

+Freescale MPC7448hpc2 (Taiga) board
+===================================
+
+Created 08/11/2006 Roy Zang
+--------------------------
+MPC7448hpc2 (Taiga) board is a high-performance PowerPC server reference
+design, which is optimized for high speed throughput between the processor and
+the memory, disk drive and Ethernet port subsystems.
+
+MPC7448hpc2(Taiga) is designed to the micro-ATX chassis, allowing it to be
+used in 1U or 2U rack-mount chassis¡¯, as well as in standard ATX/Micro-ATX
+chassis.
+
+Building U-Boot
+------------------
+The mpc7448hpc2 code base is known to compile using:
+ Binutils 2.15, Gcc 3.4.3, Glibc 2.3.3
+
+ $ make mpc7448hpc2_config
+ Configuring for mpc7448hpc2 board...
+
+ $ make
+
+Memory Map
+----------
+
+The memory map is setup for Linux to operate properly.
+
+The mapping is:
+
+ Range Start Range End Definition Size
+
+ 0x0000_0000 0x7fff_ffff DDR 2G
+ 0xe000_0000 0xe7ff_ffff PCI Memory 128M
+ 0xfa00_0000 0xfaff_ffff PCI IO 16M
+ 0xfb00_0000 0xfbff_ffff PCI Config 16M
+ 0xfc00_0000 0xfc0f_ffff NVRAM/CADMUS 1M
+ 0xfe00_0000 0xfeff_ffff PromJet 16M
+ 0xff00_0000 0xff80_0000 FLASH (boot flash) 8M
+ 0xff80_0000 0xffff_ffff FLASH (second half flash) 8M
+
+Using Flash
+-----------
+
+The MPC7448hpc2 board has two "banks" of flash, each 8MB in size
+(2^23 = 0x00800000).
+
+Note: the "bank" here refers to half of the flash. In fact, there is only one
+bank of flash, which is divided into low and high half. Each is controlled by
+the most significant bit of the address bus. The so called "bank" is only for
+convenience.
+
+There is a switch which allows the "bank" to be selected. The switch
+settings for updating flash are given below.
+
+The u-boot commands for copying the boot-bank into the secondary bank are
+as follows:
+
+ erase ff800000 ff880000
+ cp.b ff000000 ff800000 80000
+
+U-boot commands for downloading an image via tftp and flashing
+it into the secondary bank:
+
+ tftp 10000 <u-boot.bin.image>
+ erase ff000000 ff080000
+ cp.b 10000 ff000000 80000
+
+After copying the image into the second bank of flash, be sure to toggle
+SW3[4] on board before resetting the board in order to set the
+secondary bank as the boot-bank.
+
+Board Switches
+----------------------
+
+Most switches on the board should not be changed. The most frequent
+user-settable switches on the board are used to configure
+the flash banks and determining the PCI frequency.

+5. pixis_reset command
+--------------------
+A new command, "pixis_reset", is introduced to reset mpc8641hpcn board
+using the FPGA sequencer. When the board restarts, it has the option
+of using either the current or alternate flash bank as the boot
+image, with or without the watchdog timer enabled, and finally with
+or without frequency changes.
+
+Usage is;
+
+ pixis_reset
+ pixis_reset altbank
+ pixis_reset altbank wd
+ pixis_reset altbank cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
+ pixis_reset cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
+
+Examples;
+
+ /* reset to current bank, like "reset" command */
+ pixis_reset
+
+ /* reset board but use the to alternate flash bank */
+ pixis_reset altbank
+
+ /* reset board, use alternate flash bank with watchdog timer enabled*/
+ pixis_reset altbank wd
+
+ /* reset board to alternate bank with frequency changed.
+ * 40 is SYSCLK, 2.5 is COREPLL ratio, 10 is MPXPLL ratio
+ */
+ pixis-reset altbank cf 40 2.5 10
+
+Valid clock choices are in the 8641 Reference Manuals.

+ * The u-boot networking stack is a little weird. It seems like the

+ * and one TX buffer, each of which can hold a ethernet packet of
+ * maximum size.

+ * For some reason, the networking core unconditionally specifies a
