- Use armada-3720-espressobin-v7-emmc.dtb to enable both SDHCI controllers - Fix root device: /dev/mmcblk1p2 (eMMC is mmc1 with dual controller DTB) - Add modprobe.blacklist=mv88e6xxx,dsa_core to prevent DSA probe loop - Add sdhci.debug_quirks2=0x40 to fix xenon-sdhci DDR timing issues - Add initramfs hooks for sdhci-xenon and mv88e6xxx blacklist - Add systemd service to load mv88e6xxx after rootfs mount - Fix fstab tmpfs mount (remove non-existent user reference) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
