uart: allow UART_DEV_DBGPORT for fdt consoles

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.

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.

Now that we have OF_decode_addr(), with proper MD implementations, to obtain
the bus space tag and handle for a uart console, use the values returned by

Also, use OF_getencprop() instead calling fdt32_to_cpu() separately.

will allow for code that uses the old fdt_get_range and fdt_regsize
functions to find a range, map it, access, then unmap to replace this, up

As this function should only be used in the early boot code the unmap is
mostly do document we no longer need the mapping as it's a no-op, at least
on arm.

Allow us to set the console device tree node. This is needed as not all
vendor supplied device trees contain the needed properties for us to select
the correct uart to use as the kernel console.

An example of this would be to add the following to loader.conf.
hw.fdt.console="/smb/uart@f7113000"

The intention of this is slightly different than the existing
hw.uart.console option. The new option will mean the boot serial
configuration will be derived from the device node, while the existing
option expects the user to configure all this themselves.

Further work is planned to allow the uart configuration to be set based on
the stdout-path property devicetree bindings.

Add support for the uart classes to set their default register shift value.
This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.

This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

Use OF_getencprop over OF_getprop and fdt32_to_cpu. The latter may give

Arrange for uart_cpu_fdt's probe() routine to use the same table of compat

The bus code uses ofw_bus_search_compatible() and that's not an option in
cpu (console) code -- it runs way before the ofw routines are usable. So
the console probe has its own loop to search the table, but now at least
there's only one table to be maintained when new devices are added.

better than no console.
