4d846d260e spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD
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.

94bc2117b4 Add i.MX 8M Quad support
- Add CCM driver and clocks implementations for i.MX 8M
- Add GPC driver for iMX8
- Add clock tree for i.MX 8M Quad
- Add clocks support and new compat strings (where required) for existing i.MX 6 UART, I2C, and GPIO drivers
- Enable aarch64-compatible drivers form i.MX 6 in arm64 GENERIC kernel config
- Add dtb/imx8 kernel module with DTBs for Nitrogen8M and iMX8MQ EVK

With this patch both Nitrogen8M and iMX8MQ EVK boot with NFS root up to multiuser login prompt

718cf2ccb9 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.

405ada37fb 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.

c3f0f2847f Return the actual baud rate programmed in the hardware rather than 115200.
This allows the "3wire" entry in /etc/ttys (with no speed specified) to work.

2d40ec16a8 Flesh out imx_uart_init() so that we're not relying on u-boot to init
the hardware (meaning uarts other than the console will work).

a90f19753f The freescale imx uart driver works for the whole i.MX family, so rename the
header file to not have "5xx" in the name.

d76a1ef4e1 Introduce grab and ungrab upcalls. When the kernel desires to grab the
console, it calls the grab functions. These functions should turn off
the RX interrupts, and any others that interfere. This makes mountroot
prompt work again. If there's more generalized need other than
prompting, many of these routines should be expanded to do those new
things.

Should have been part of r260889, but waasn't due to command line typo.

4d7abca057 Fix low-level uart drivers that set their fifo sizes in the softc too late.
uart(4) allocates send and receiver buffers in attach() before it calls
the low-level driver's attach routine.  Many low-level drivers set the
fifo sizes in their attach routine, which is too late.  Other drivers set
them in the probe() routine, so that they're available when uart(4)
allocates buffers.  This fixes the ones that were setting the values too
late by moving the code to probe().
