The vendor prefix and the board are documented and basic SoC/board devicetrees are added. I've successfully booted into console with vendor U-Boot, a bootlog could be obtained here[1]. DTB and initramfs must be built into the kernel as the vendor bootloader cannot pass them and upstream U-Boot support for LoongArch is still WIP. Thanks for your time and review.
