linux-mt6000: Nonguix linux 6.17 with ARCH_MEDIATEK and the MT7986 drivers, OpenWrt's block NVMEM provider and mac-base patches (WiFi calibration and MACs from the eMMC factory partition), bootargs-append, and OpenWrt's GL-MT6000 device tree. mt6000.scm: the Pi's OpenWrt userland on the MT6000 (lan1-5 + WiFi in br-lan, eth1 WAN). Shared pieces move to packages/router-base.scm; the Pi's system is unchanged. build-mt6000-root.sh builds the ext4 root for the rootfs partition and, with scripts/mt6000-fit.sh, the FIT that GL's U-Boot boots from the kernel partition -- for the system inside the image, whose root is the partition's UUID.
