Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
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.
additions to sys/amd64/isa/icu.h from PIIX4 and other datasheets. I
tweaked a few comments based on the NetBSD header of the same name when I
merged the constants to sys/i386/isa/icu.h, but the vast majority of this
file was created independently by Peter and not taken from any existing
files.
