SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

test: eth: Add a test for ARP requests This tests that ARP requests made to this target's IP address are responded-to by the target when it is doing other networking operations. This currently corrupts the ongoing operation of the device if it happens to be awaiting an ARP reply of its own to whatever serverip it is attempting to communicate with. In the test, add an expectation that the user operation (ping, in this case) will fail. A later patch will address this problem.
