- fix bootorder (SD -> NVMe -> eMMC); USB disabled as nonworking with mainline still
- use the DT from rockchip64-6.18 so a single source for both u-boot and kernel
- note: the first (and only) RTL8169 used by u-boot is the port closest to board edge
- using the same DT as the rockchip64-6.16
- defconfig based on Rock5b, so we can eventually use the same fusb302 when time comes
- -u-boot.dtsi enables `ums` / `rockusb` et al using the middle usb-c port (orientation sensitive)
- enables booting from NVMe
- TODO: sd/usb/nvme/mmc boot order
- 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
Switch to newer U-Boot since it works reliably and provides upstream
improvements.
Add patch/u-boot/v2025.10 and the generic patch, as BOOTPATCHDIR cannot
be unset (fallback to legacy fails).
BOOT_SCENARIO="binman-atf-mainline" cannot be set here since it applies
globally to the CSC file and would break branch=vendor. Users who want
it can enable it manually.
