Hi,
I tried to test the Linux RISC-V UEFI stub by cross-compiling this
branch with binutils 2.34 and GCC 9.3.0:
https://github.com/atishp04/linux/tree/uefi_riscv_pr
It results in a segfault in ld while linking vmlinux because the pointer
h->root.u.def.section is NULL in one instance. This change fixes the
segfault and results in a usable UEFI kernel, but I am not familiar with
this code, so I don't know if it is the correct behavior.
Can someone verify this? Let me know if you need configs etc.
Thanks.
David
