Originally reported by Nathaniel Hourt[1], U-Boot fails to boot on JH7110 platforms (starfive_visionfive2_defconfig) when building with Clang.
This series fixes configuration generation with Clang's preprocessor and add an alternative codepath for RISC-V to access gd to workaround misoptimization of Clang, which is sufficient for building images for JH7110 boards. Tested with - starfive_visionfive2_defconfig - qemu-riscv64_smode_defconfig - sifive_unleashed_defconfig built with either GCC 14 or LLVM 19. Note that images built with LLVM lld are still broken and binutils ld has to be used for now. To test the changes on JH7110 platforms, this patch[2] must be applied for SPL to function.
