      ppc44x: Unification of virtex5 pp440 boards · e07f4a80
      Ricardo Ribalda Delgado authored 
      
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 'license' command to U-Boot command line · 0a823aa2
      Harald Welte authored 
      
The 'license' command includes the U-Boot license (GPLv2) into the
actual bootloader binary. The license text can be shown interactively
at the U-Boot commandline.

For products where the commandline can actually be accessed by the
end user, this helps to prevent inadvertent GPL violations, since the
GPLv2 license text can no longer be 'forgotten' to be included into
the product.

The 'license' command can be enabled by CONFIG_CMD_LICENSE.
