The Spacemit Version of OpenSBI is outdated and disabled printf and consumes the wrong dts with wrong isa string, causing some debugging features that needs printf does not work, and zicboz can not be activated.
This file will tell you how to replace OpenSBI to mainline (v1.4+) on Spacemit K1, and it also compatible with factory sdk kernel.
You have flashed Bianbu or Armbian for BPI-F3 and flashed to SD Card.

We can trust the use of _dl_lookup_symbol_x during elf_machine_runtime_setup in SHARED is safe
These discussions are based on recent glibc commit a4c414796a.
I know it's hard to prove _dl_lookup_symbol_x being called at elf_machine_runtime_setup without l_relocated == 1 when we have #ifdef SHARED is safe. But if we trust another place it is being called is safe, and there is no change for the requested data structure between these 2 times , then it's natural to trust we call it here is safe.
We can prove this by debugging lib/ld-linux-riscv64-lp64d.so.1 in gdb. First, compile glibc commit a4c414796a with && l->l_relocated removed in sysdeps/riscv/dl-machines.h.
Tested on LoongArch Archlinux (2023-10-09).
