Add busy detect quirk to list of console options

2018-07-22T23:32:21Z

This change allows one to set the busy_detect flag required by the synopsys UART at the loader prompt. This is needed by the EPYC 3000 SoC. This will give users a working console up to the point where getty is required: hw.uart.console="mm:0xfedc9000,rs:2,bd:1" Reviewed by: imp MFC after: 4 weeks Differential Revision: https://reviews.freebsd.org/D16399

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.

Allow setting access-width for UART registers.

2017-02-27T20:08:42Z

This is required for FDT's standard "reg-io-width" property (similar to "reg-shift" property) found in many DTS files. This fixes operation on Altera Arria 10 SOC Development Kit, where standard ns8250 uart allows 4-byte access only.

(class and device) FDT UART. Define second one, UART_FDT_CLASS, for UART class only. This paves the way for declaring uart_class data and ofw/fdt compat data with a uart implementation, rather than needing a big global table of compat data and weak-symbol declarations of every existing implementation.
