Hi Marek,
Hi,
Clean up the screaming mess of configuration options that DFU is. It was impossible to configure DFU such that TFTP is enabled and USB is not, this patch fixes that and assures that DFU TFTP and DFU USB can be enabled separatelly and that the correct pieces of code are compiled in.

No, it just follows suit with the already messed up naming. But I have a subsequent patch doing
dfu: Rename _FUNCTION_DFU to DFU_OVER_
Do the following to make the symbol names less confusing.
sed -i "s/([TU][^_]+)_FUNCTION_DFU/DFU_OVER_\1/g" \ `git grep _FUNCTION_DFU | cut -d ":" -f 1 | sort -u`
This should make the purpose clear.

Please exclude relevant pieces of code for TFTP and for USB in a separate static functions:
#ifdef CONFIG_USB_FUNCTION_DFU dfu_usb() {
} #else dfu_usb() {return 0}; #fi
#ifdef CONFIG_DFU_TFTP dfu_tftp() {
} #else dfu_tftp() {return 0}; #fi
do_dfu () { ... ret = dfu_usb(); ret = dfu_tftp(); .... }
This is kinda hard to split, but let's see.
return ret; }

Please simply use (in a way similar to ./cmd/mmc.c) :
This does not work, you see, if you use U_BOOT_CMD it prefixes only the first entry with the command name. Not the subsequent entries. That's why this extra ifdef is needed.
The code below, triggered by help dfu, would print "dfu dfu tftp" if CONFIG_USB_FUNCTION_DFU was disabled.
#ifdef CONFIG_USB_FUNCTION_DFU "<USB_controller> <interface> <dev> [list]\n" " - device firmware upgrade via <USB_controller>\n" " on device <dev>, attached to interface\n" " <interface>\n" " [list] - list available alt settings\n" #endif #ifdef CONFIG_DFU_TFTP "dfu tftp <interface> <dev> [<addr>]\n" " - device firmware upgrade via TFTP\n" " on device <dev>, attached to interface\n" " <interface>\n" " [<addr>] - address where FIT image has been stored\n" #endif

This shall be left as it is - Faiz is going to clean up this. http://patchwork.ozlabs.org/patch/873372/
And side question - the CONFIG_SPL_DFU_SUPPORT shall be orthogonal to other DFU settings (as it is for SPL).
Does your board require DFU support in SPL ?
No, but I also don't want to break other boards.

So is this. It's another crutch to prevent this mess from completely unraveling.

I do like the idea of first enabling CONFIG_CMD_DFU, which then if applicable enables USB_FUNCTION_DFU or DFU_TFTP.
Also CONFIG_DFU shall add generic drivers/dfu/dfu.o.
