Custom Talos Linux images for Raspberry Pi 5 / CM5 on Compute Blade hardware.

The official Talos Image Factory does not support CM5 — the mainline kernel lacks CM5 device trees and RP1 driver support. This builder uses the RPi downstream kernel (via [talos-rpi5/talos-builder](https://github.com/talos-rpi5/talos-builder) patches) to produce working CM5 images with our extensions and overclock config.

|
|
|
|
```bash
|
|
zstd -d metal-arm64.raw.zst -o metal-arm64.raw
|
|
# Flash to eMMC/SD via your preferred tool (dd, balenaEtcher, etc.)
|
|
```
|
|
|
|
### Upgrade an existing node
