Hi, experts: I found DFU tool code had been put in drivers/dfu directory. Previously, it was owned by Samsung Electronics.
Could you be more specific here?

Which clearly states that the code is GPL v2+. The code is "open", you can modify it and use with your product if you provide your's product source code when requested.
Because it has been merged into uboot library. So, it could be used or released by every ARM SOC vendor?
Yes, it can as long as this vendor sticks to GPL v2 license. This mean (with some simplification :-) ) that this vendor needs to publish source code for his product.
