Where can I find the full (GPL compliant) sources of the BSP?
The BSP linked in the docs (GitHub - BPI-SINOVOIP/BPI-RV2-SF21H8898-OPENWRT-BSP)
seems to be very incomplete.
It misses at least the sources for the bootloader nor does it build openwrt-siflower-sf21h8
898-bpi-rv2-nand-squashfs-fullflash.img.
