- materialized overwrites:
- `add-board-helios64.patch`
- `add-board-orangepi-r1-plus.patch`
- `add-driver-for-Motorcomm-YT85xx+PHYs.patch`
- `add-board-rk3328-roc-pc.patch`
- not touched: wifi patches, those still require work before rebase is consistent.
- `wifi-4003-uwe5622-adjust-for-rockchip.patch`
- this patch is done on top of the wifi drivers patches exclusively, and fails to apply out of tree.
- we should probably consider moving this into the wifi drivers patch harness, not in the rockchip tree.
