So just finished the above cycle and flashed sdcard.  Think we got somewhere this time!

I get only one instance of sdma error:

[    0.117495] EINJ: ACPI disabled.     
[    0.126332] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2

[    0.134253] mxs-dma 33000000.dma-controller: initialized                     
[    0.135378] Bus freq driver module loaded

... of note here is it didn't say it was using ROM version!!!!

And I have firmware package for sdma now:

root@imx8mmevk:~# rpm -qa | grep -i firmware
linux-firmware-ath10k-license-20200817-r0.noarch
firmware-qca9377-3.0.2-r0.noarch
firmware-imx-epdc-8.8-r0.noarch
linux-firmware-ath10k-20200817-r0.noarch
firmware-imx-sdma-imx7d-8.8-r0.noarch


root@imx8mmevk:/lib/firmware# ls -l

drwxr-xr-x    3 root     root          1024 Mar  9 12:34 wlan

... and /lib/firmware/imx/sdma looks like:

root@imx8mmevk:/lib/firmware/imx/sdma# ls
sdma-imx7d.bin

So hopefully this helps with the ALSA issue I was chasing that led me to this sdma issue in the first place!

Thanks guys!  I don't know why core-image-minimal isn't working ... I see there is a
firmware-imx-8m package so maybe I should add it.
