- this maps copying files from dirs in the patch directory directly to the u-boot tree, without any .patch required:
- `defconfig` -> `configs` (useful for all)
- `dt_uboot` -> `arch/arm/dts` (useful for most; use for xx-u-boot.dtsi or stuff without CONFIG_OF_UPSTREAM)
- `dt_upstream_rockchip` -> `dts/upstream/src/arm64/rockchip` (useful for Rockchip boards)
- other mappings (eg `dt_upstream_xxx`) might be added later
