Why is modification of the generic at91 led code required? It is not clear.
Please, only make a patch series with only USB-DFU stuff in it, drop the add-board code from this series. The board code is not acceptable for mainstream since it does not follow the new u-boot-atmel->rework110202 tree style of adding at91 boards. It will take you a huge amount of effort to make it suitable. Further, both parts of the patch series are not related and you are now creating a link between the Atmel tree and the USB tree, which makes it even more difficult.
Kind regards,
Remy

I optionally use the LED's in DFU mode so that there's interaction while upgrading the board. You might believe the host could handle this, but I like the device to indicate activity as well. Somehow I couldn't get it working without changing led.c I think, but I may have missed something.

Already noticed that.

I'm actually busy fixing the board code for u-boot-atmel->rework110202
Most of it is working so I hope I can create the patches as you like them.

U-boot has a terminal/monitor. It is not up to the driver to control LEDs that might or might not be on a board.

The problem is here that you mix up sub-systems. Modifying LED code should be independent from USB driver code, and really not in the same patch.
common/Makefile | 1 + common/update_dfu.c | 2 - drivers/usb/gadget/usbdfu.c | 14 +++--
These files should be completely generic code, that even would work on X86, PowerPC and so on.
drivers/usb/gadget/atmel_usba_udc.c | 8 +-
Only this driver file should be Atmel USBA specific, but NOT SoC specific, and absolutely not board or board config related.

Hmm, Let's make it even more black/white: I do not have to like the board code. ;-) Reinhard is the Atmel maintainer. He needs to pull in the Board code. I only care about generic USB code... ;-)))
Please make 2 unrelated patch series (1 series for USB DFU support, 1 series for board support), or it will never hit mainline... AND: I would really recommend to build a decent USB/DFU patch series first. Forget the board for now. The board seems to depend on DFU support, not the other way around. If generic DFU code is really generic and acceptable, I will pull it in my tree. I am willing to fix small issues in the series to assist you, but I will not do major redesigns...
Kind regards,
Remy

OK, good to know. I'll check that out, but not today. For now I can remove the LED code I think. Than in a couple of months I can can check how to use the monitor code.

Agree on that. It would be optiomal. Not everything is, the first time :-)

hmmm. The black and white this is that after today I don't have a single hour to spend on this code :-)

Well, the board does not depend on DFU. Not even the USBD controller is activated in the board config. It is left up to a script to handle that though update_dfu.c which defines a command for that. I may have left some parts in that don't really belong there, I haven't check it yet.

Dear Remy and Reinhard,

I tried compiling everything against the rework tree. Unfortunately I don't know how to solve the reset_timer issue and my NAND won't work. Although Reinhard just commented on that, I have no clue yet how to fix it.
I can't finish this work today and really have no time left for it, so I have to quit on the code for now.
I will have to thank you for you assistance for now and have to get back on this in a couple of months if I do find the time again.
Hopefully someone picks up the v2 patch and continues from there. It's not very difficult to make it work in Reinhard's tree I think.
Best regards, Marcel
