It's no longer used since 58aa35d42975c298ca0adba705c042596303c9f5 and r357455 respectively.

[PowerPC] Fix scc z8530 driver

2020-06-14T16:47:16Z

Parts of the z8530 driver were still using the SUN channel spacing. This was invalid on PowerMac and QEMU, where the attachment was to escc, not escc-legacy. This means the driver has apparently NEVER worked properly on Macintosh hardware. Add documentation for the channel spacing details, and change to using driver-specific initialization instead of hardcoded spacing so either spacing can be used. Fixes boot hang in QEMU when using the serial console, and fixes use on Xserve serial (and presumably PowerMacs that have a Stealth Serial port or similar) Reviewed by: jhibbits Sponsored by: Tag1 Consulting, Inc.

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

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.

Mainly focus on files that use BSD 3-Clause license. 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.

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

- Remove i8255.h because it's pc98 device.

2017-01-29T03:34:49Z

- rsa.h is for both RSA-DV/S ISA and RSA-98III CBUS, but there is no RSA-DV/S support. So it can be removed.

Remove pc98 support completely.

2017-01-28T02:22:15Z

I thank all developers and contributors for pc98. Relnotes: yes
