Severity: normal
The iMX8 SoC is used on various boards, widely available to debian
users and well supported by free software, but the platform is not
enabled in debian kernels, which is a rather major omission. I don't
know why not (I guess no-one filed this bug?).
These are all avilable today and should at least mostly work with
mainline:
Nitrogen 8M
https://boundarydevices.com/product/nitrogen8m/
Solidrun
Cubox M https://shop.solid-run.com/product/SRMP8QDWB1D04GE008X00CE/
Hummingboard Pulse https://shop.solid-run.com/product-category/embedded-computers/nxp-family/hummingboard-m/
Purism
Librem 5 Phone https://en.wikipedia.org/wiki/Librem_5
Compulab
SBC-iMX8X https://www.compulab.com/products/sbcs/sbc-imx8x-nxp-i-mx-8x-single-board-computer/
(supported since 5.4.24)
Toradex
Apalis iMX8 CoM https://www.toradex.com/computer-on-modules/apalis-arm-family/nxp-imx-8
I believe that all that is needed is adding
CONFIG_ARCH_MXC=y in debian/config/arm64/config
Which is set by default upstream.
(There may be other drivers that should enabled too for some of these
platforms?)
I just built the kernel with the above config change and it builds
fine on arm64, and installs and boots on softiron. I don't have an
iMX8 here to test on, but we can find some, I'm sure.
It seems like the timing was rather unfortunate here with some of this
hardware only becoming widely available in Q4 2020 (shortly before the
Bullseye freeze). Is there any chance of one more hardware enablement
upload for bullseye, or does this feel like too big a change? If not,
getting this into a point release would make debian stable useful on a
lot more hardware. What testing would make the kernel team reasonably
happy about doing that?

I enabled a few more settings in our sid branch. See

I have an i.MX8 here, but didn't do any tests (yet).

Source: linux
Version: 5.10.26-1
Followup-For: Bug #985862
Testing 5.10.26-1 on a Compulab IOT-gateway board (https://www.compulab.com/products/iot-gateways/iot-gate-imx8-industrial-arm-iot-gateway/) revealed that a couple more config options are needed to support it:
CONFIG_SERIAL_IMX_CONSOLE=y
CONFIG_CLK_IMX8MM=y
Without these it hangs early in the boot process.
(Whilst they can be configured as modules this doesn't work
well. CONFIG_SERIAL_IMX_CONSOLE=m misses quite alot of the boot
messages and CONFIG_CLK_IMX8MM=m just makes it hang.)
(Thanks to Vincent for the testing)
Enabling these in the next upload, whenever that is, would be much appreciated.
Addendum:
There are almost certainly some other clocks needed for other hardware, but that
needs to await testing/feedback from people with access to said hardware.
Just for future reference: I believe the correspondance of config options to SOC variants is:
IMX8MN == i.MX8M Nano
IMX8MQ == i.MX8M Quad
IMX8QXP == i.MX8 QuadXPlus
IMX8MP == i.MX8M Plus

Hi,
Thanks Wookey for the testing feedback. This really starts to become
late for the bullseye release, so we need to be careful enough. We
will see what we can do.

Understood. I see we were just 2 days too late for the 5.10.28 update,

which is unfortunate - that would have worked nicely.
I think it's fairly safe, and it's been upstream and enabled there for
a while, but of course you never know...
If this has to end up in the first point release after bullseye then that's fair enough.
