As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx
ppc440 boards, this patch presents a common architecture for all the
xilinx ppc405 boards.
Any custom xilinx ppc405 board can be added very easily with no code
duplicity.
This patch also adds a simple generic board, that can be used on almost
any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h
This patch is prepared to work with the latest version of EDK (10.1)

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.

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
