* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=326255
* Make tsec work with the device tree present on the RB800. The previous codeNathan Whitehorn2013-11-111-6/+7
| | | | | | | | | | | assumed that the MDIO bus was a direct child of the Ethernet interface. It may not be and indeed on many device trees is not. While here, add proper locking for MII transactions, which may be on a bus shared by several MACs. Hardware donated by: Benjamin Perrault Notes: svn path=/head/; revision=257993

* Support for Freescale integrated Three-Speed Ethernet Controller (TSEC).Rafal Jaworowski2008-03-031-0/+355
TSEC is the MAC engine offering 10, 100 or 1000 Mbps speed and is found on different Freescale parts (MPC83xx, MPC85xx). Depending on the silicon version there are up to four TSEC units integrated on the chip. This driver also works with the enhanced version of the controller (eTSEC), which is backwards compatible, but doesn't take advantage of its additional features (various off-loading mechanisms) at the moment.
