Looks like the Note 10.1 tablet has the ability to run mainline linux and there is someone with the device that is actively working to get Android 10 running with mainline on it: https://github.com/CustomROMs/android_local_manifests_i9300/issues/1#issuecomment-568949705

I added Viciouss' downstream dts here: https://redmine.replicant.us/projects/replicant/wiki/Upstream#Other-devices-with-some-upstream-support and I added a row for bootloader info here: https://redmine.replicant.us/projects/replicant/wiki/Upstream#Bootloader-status

Both sections need more information added.
