Re: [U-Boot] [PATCH] add board support for virtex4fx12 minimodul

9 Sep 2008

Hello Ricardo,
thanks for your comments.  i have some more questions :
...

The board is manufactured by avnet, you must create it under the

folder boards/avnet/fx12mm
your are right, i will move it
...

Try to unificate the fx12mm board under a more global board, like

the ml507 with is now in mainstream
you mean, that i create only a new config file and use the ml507 board 
code ?
is this better than create new board specific files under 
board/avnet/fx12mm ?
...

There are some object that are not used (or I don't see where are

they used) in your makefile. (../common/*)
ups, i clean it up. its correct, the objects are not used
regards
georg
