The question isn't whether it's royalty free or not.
The question is rather, whether ARM can sue us for breaking the law by using 
the AXI4 bus inside our ASICs, which we might also sell to customers the US 
government doesn't like. Or plain: Is it free or is it unfree?
Can we use it without patent issues?
Does ARM still require us to get a license from them in order to use it?
If yes we might be in quiet a bit of a trouble here, because we can't 
guarantee to fulfill the standard clauses in US export agreements.
We need someone to check before we start developing and selling products based 
on this interface.
Not that I worry too much about possible sanctions from the US because we 
still have access to the whole Chinese market.
And no one at the border will be able to check, whether these manufacturers 
from Shenzhen have soldered our chips onto their PCBs or not.
But ironically my partners from China worry about avoiding legal issues with 
the united states.
