Does this mean I need to build my own i.MX8 image or are NXP processors not supported in aarch64? I tried searching the mailing list archive on marc, but there were no search results for mx8 or imx8.

I am running FreeBSD current on a NXP LS1088a with no issues.  (8 core A-53) Looking in the kernel source, I see:

sys/arm64/freescale/imx/imx8mq_ccm.c
sys/arm64/freescale/imx/imx8mq_ccm.h

There are also a lot of mx8 files under sys/contrib/device-tree/src/arm64/freescale so I would think you should be able to get something working.

NPU - neural processing unit.  Taking a quick look through the source, it appears that there is no support for this.
