TX2 Support

[Wulfsta]

This is not a feature request, but I am curious what work would need to be done to add support for the Jetson TX2? I dug one out of storage recently and would love to run NixOS on it.

We'd have to package Jetpack 4, which has enough differences compared with Jetpack 5 (old kernel, different bootloader) that I opted not to try. This could possibly be done by adding enough conditionals everywhere to capture the differences between Jetpack 4 and Jetpack 5. I haven't really looked closely at what would be required for this to happen.

However, when Jetpack 6 is released, it is expected to drop support for Xavier AGX and Xavier NX, and I'd like to keep Xavier AGX/NX support continuing, so at that time, we'll have to have some level of support for multiple versions of Jetpack.

A year have passed, what is your current support strategy for Xavier? If two jetpack releases are to be supported, is there any interest in TX1/2?
