- similar to `rkdevflash`, but for Mediatek devices
- also simpler; lk.bin & fip.img are produced by image build and directly used
- requires Rust+Cargo, so add those to hostdeps
- since this is a core extension, those will be included in all Docker images too
- which was bound to happen anyway since Rust in Linux Kernel is no longer an experiment
- extensions/mtkflash: sha1-based bin path, use fork & add `--no-erase-boot1`
- example invocation:
- `BOARD=radxa-nio-12l BRANCH=collabora RELEASE=trixie EXT=ufs,mtkflash MTKFLASH_TTYACM_DEVICE=1`
