Now that FlexCAN emulation has landed in master, let's add it to imx8mp-evk as well. While the real i.MX8M Plus supports CAN FD which isn't emulated yet, the non-FD mode works well under Linux: It is possible to use `cangen` and `candump` either way on the host and on the guest, as described in docs/system/devices/can.rst. This series consists of five patches where the first four are preparations. The last patch integrates FlexCAN into the i.MX8M Plus SoC and EVK board. The first preparation addresses the review comment from [1], and could be applied independently. It would be nice if this series could make it into 11.1. Testing done: * Start imx8mp-evk and run `cangen can0` there. Observe on the host that `candump vcan0` prints the traffic. * `make check` v2: Thanks for the very helpful and super quick review, Phil! Here we go: * Add patch "hw/net/can/flexcan: Wire clock control module via link property" * Have separate MemoryRegionOps for 32 and 64 bit [1] https://lore.kernel.org/qemu-devel/77d5891c-de12-467e-8746-02fe43121e3e@oss.qualcomm.com/ --- base-commit: a59157f98f0b69b0bbdb26bc15fbc4d6c8060799 Bernhard Beschow (5): hw/net/can/flexcan: Wire clock control module via link property hw/net/can/flexcan: Subclass TYPE_CAN_FLEXCAN hw/arm/imx8mp-evk: Open code DEFINE_MACHINE_AARCH64 hw/arm/imx8mp-evk: Introduce FslImx8mpEvkState hw/arm: Add basic FlexCAN3 support to TYPE_FSL_IMX8MP and imx8mp-evk docs/system/arm/imx8m.rst | 1 + include/hw/arm/fsl-imx8mp.h | 8 ++++ include/hw/net/flexcan.h | 4 +- hw/arm/fsl-imx6.c | 5 ++- hw/arm/fsl-imx8mp.c | 38 ++++++++++++++++ hw/arm/imx8mp-evk.c | 64 ++++++++++++++++++++++----- hw/misc/imx8mp_ccm.c | 3 ++ hw/net/can/flexcan.c | 88 ++++++++++++++++++++++++++++++------- hw/arm/Kconfig | 1 + 9 files changed, 182 insertions(+), 30 deletions(-) -- 2.55.0

As you note, I've already sent the last target-arm PR for pre-freeze yesterday; I'm not going to do another one. So from my POV this has just missed the deadline and will have to wait for 11.2. thanks -- PMM

Thanks for the work. I have tested the series on the top
of your imx8mp-flexcan branch, commit
3b7289419cac5b712faeadf6b4a6203579d08f76
with our test setup for iMX6
qemu-system-arm -m 1G -M sabrelite -smp 4 ...
and it worked as intended. I have looked at all patches
from your series and I do not see anything problematic.
You can add my confirmation to the series and or individual
patches

By the way, I have noticed your iMX53 branch. We have some
old kits for this because we used it for yet another generation
of medical infusion system prototypes/instruments fully
functional demonstrators but before final HW design with
safety.

I haven't decided yet whether to upstream it because I wonder if anyone would be interested in this rather old but (IIUC) longterm SoC.
