      ppc44x: Unification of virtex5 pp440 boards · e07f4a80
      Ricardo Ribalda authored and Stefan Roese's avatar Stefan Roese committed 
      
This patch provides an unificated way of handling xilinx v5 ppc440 boards.

It unificates 3 different things:

1) Source code
A new board called ppc440-generic has been created. This board includes
a generic tlb initialization (Maps the whole memory into virtual) and
defines board_pre_init, checkboard, initdram and get_sys_info weakly,
so, they can be replaced by specific functions.

If a new board needs to redefine any of the previous functions
(specific initialization) it can create a new directory with the
specific initializations needed. (see the example ml507 board).

2) Configuration file
Common configurations are located under configs/xilinx-ppc440.h, this
header file interpretes the xparameters file generated by EDK and
configurates u-boot in correspondence. Example: if there is a Temac,
allows CMD_CONFIG_NET
Specific configuration are located under specific configuration file.
(see the example ml507 board)

3) Makefile
Some work has been done in order to not duplicate work in the Main
Makefile. Please see the attached code.

In order to support new boards they can be implemented in the next way:

a) Simple Generic Board  (90% of the time)
Using EDK generates a new xparameters.h file, replace
ppc440-generic/xparameters.h  and run make xilinx-ppc440-generic_config
&& make

b) Simple Boards with special u-boot parameters (9 % of the time)
Create a new file under configs for it (use ml507.h as example) and
change your paramaters. Create a new Makefile paragraph and compile

c) Complex boards (1% of the time)
Create a new folder for the board, like the ml507

Finally, it adds support for the Avnet FX30T Evaluation board, following
the new generic structure:

Cheap board by Avnet for evaluating the Virtex5 FX technology.

This patch adds support for:
 - UartLite
 - 16MB Flash
 - 64MB RAM

Prior using U-boot in this board, read carefully the ERRATA by Avnet
to solve some memory initialization issues.

      Add support for the hammerhead (AVR32) board · 5c374c9e
      Julien May authored 
      The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel.  It offers versatile peripherals, such as ethernet, usb
device, usb host etc.

The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).

Additonally, a Cyclone III FPGA from Altera is integrated on the board.
The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
DDR2 SDRAM interfaces, which will cover even the most exceptional need
of memory bandwidth. Together with the onboard video decoder the board
is ready for video processing.

      ppc4xx: ML507 Board Support · 086511fc
      Ricardo Ribalda authored and Stefan Roese's avatar Stefan Roese committed 
      
The Xilinx ML507 Board is a Virtex 5 prototyping board that includes,
	among others:
	-Virtex 5 FX FPGA (With a ppc440x5 in it)
	-256MB of SDRAM2
	-32MB of Flash
	-I2C Eeprom
	-System ACE chip
	-Serial ATA connectors
	-RS232 Level Conversors
	-Ethernet Transceiver

This patch gives support to a standard design produced by EDK for this
board: ppc440, uartlite, xilinx_int and flash

- Includes Changes propossed by Stefan Roese and Michal Simek
