Could you do me a favour and add a SPDX license identifier in front of the 
license boilerplate codes?

It's not required for the QEMU project, but at least I normally have 
troubles to find out what such longer license boilertexts mean ... is it a 
BSD license, is it a MIT license, something completely else...? A short SPDX 
line at the beginning helps to identify the license at a first glance.
