While we only support 4-byte registers in the uart code the physical
access may be to an 8-byte register. Support this as an option on
non-i386. On i386 we lack the needed 8-byte bus_space functions.
ACPI has an option for 8-byte register io width, and FDT can be given
any size. Support these sizes, even if we don't expect to see hardware
with an 8-byte io width.

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.

Add busy detect quirk to list of console options2018-07-22T23:32:21ZMatt Macymmacy@FreeBSD.org2018-07-22T23:32:21Zurn:sha1:f30f0f2b4792e63ffa8d07e2e791122bfb20fdbf
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"

sys/dev: further adoption of SPDX licensing ID tags.2017-11-27T14:52:40ZPedro F. Giffunipfg@FreeBSD.org2017-11-27T14:52:40Zurn:sha1:718cf2ccb9956613756ab15d7a0e28f2c8e91cab
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.2017-02-27T20:08:42ZRuslan Bukinbr@FreeBSD.org2017-02-27T20:08:42Zurn:sha1:c214a270f501ce3711165c0d18f55733bcc0ca93
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.
