Yet another update.  I further modified my  machine .conf to remove .dtb's
and features I didn't need and finally got the board booting 5.10.18!  When
I dd the wic image to sdcard it wouldn't boot so I've got a u-boot issue
somewhere but I wrote previous version of u-boot with dd and was able to
get it to boot.

Thank you all for putting up with me once again and keeping me out of the
weeds.

Now the work begins trying to get some net-next stuff working.

Regards,

Brian
