spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+00:00

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

Remove "All Rights Reserved" from FreeBSD Foundation sys/ copyrights

2021-08-08T14:42:24+00:00

These ones were unambiguous cases where the Foundation was the only
listed copyright holder (in the associated license block).

uart: allow UART_DEV_DBGPORT for fdt consoles

2020-12-02T21:01:52+00:00

Allow fdt devices to be used as debug ports for gdb(4).

A debug console can be specified with the "freebsd,debug-path" property
in the device tree's /chosen node, or using the environment variable
hw.fdt.dbgport.

The device should be specified by its name in the device tree, for
example hw.fdt.dbgport="serial2".

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

2017-11-27T14:52:40+00:00

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.

2017-02-27T20:08:42+00:00

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.

We will be switching to a new arm64 uart cpu driver that handles both FDT

and ACPI. As such pull out what will be the common parts of the FDT cpu
detection to a new function that can be shared between them.

Stop including machine/fdt.h from the fdt uart code, it's unneeded.

Do not include fdt.h on RISC-V.
