make_dtb: Always add root directory in the include path

2018-08-23T13:23:21Z

Some arch like arm and arm64 share DTS files, add the root dts directory to the include paths.

Add dtb overlays support

2018-03-24T21:30:24Z

DTB Overlays are useful to change/add nodes to a dtb without the need to modify it. Add support for building dtbo during buildkernel. The goal of DTBO present in the FreeBSD source tree is to fill a gap in time when we submit changes upstream (Linux). Instead of waiting 2 to 4 months we can add a DTBO in tree in the meantime. This is not for adding DTBO for capes/hat/addon boards, those will be better to put in a ports. This is also not for enabling a i2c/spi/pwm controller on certain pins, each user have a different use case for those (which pins to use etc ...) and we cannot have all possible configuration. Add a dtbo for sun8i-h3-sid which add the SID node missing in upstream dts. Reviewed by: kevans Differential Revision: https://reviews.freebsd.org/D14782

Avoid using \$. It's an unknown escape sequence. Some awks warn about

that. Instead, simply remove the sequence entirely because we never commit the generated files.

Teach makeobjops.awk to accept PROLOG and EPILOG blocks before

METHOD and STATICMETHOD declarations; that code will be inserted into the dispatch function before and after the method call. Use this functionality and the TSLOG framework to record DEVICE_ATTACH and DEVICE_PROBE entry/exit timestamps.

embed_mfs: support embedding mfs into loader

2017-12-19T19:44:06Z

The script originally supported embedding an mfs into ELF files or any other type of file, because it searched for magic strings to mark the beginning and end of the embeddable section. It was later modified to read the section offset and length via readelf, which made it work for ELF only. Restore the ability to update arbitrary file types by using the readelf technique for ELF, and the magic string technique for all others (including PE/COFF files like loader.efi).

sys: general adoption of SPDX licensing ID tags.

2017-11-27T15:23:17Z

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. No functional change intended.

sys: further adoption of SPDX licensing ID tags.

2017-11-20T19:43:44Z

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.

Move sys/boot/fdt/dts to sys/dts and adjust scripts.
