Pedro F. Giffuni df57947f08 spdx: initial adoption of licensing ID tags. 
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.

RelNotes:	yes

* Register definitions for the VIA VT6122 gigabit ethernet controller.
* Definitions for the built-in copper PHY can be found in vgphy.h.
*
* The VT612x controllers have 256 bytes of register space. The
* manual seems to imply that the registers should all be accessed
* using 32-bit I/O cycles, but some of them are less than 32 bits
* wide. Go figure.
