Note I think this is going to run afoul of grub2 mkimage.
In binutils-2.40 the assembler for risc-v was changed to use CALL_PLT
relocations rather than CALL relocations. grub2 does not handle
CALL_PLT relocations which in turn will cause a failure when
grub2-mkimage is used on risc-v.
As far as I can tell, the assembler change literally just changes the
relocation number, they are otherwise treated the same. So I think
grub2 can be fixed by just treating R_RISCV_CALL_PLT just like
R_RISCV_CALL in kern/riscv/dl.c.
Nelson, can you confirm that all your assembler change did was change
the relocation used in the resultant object?
The binutils change is here

I tried something like this

I still get
| grub-mkimage: error: relocation 0x13 is not implemented yet.
need to look more.
That's what I would think the right fix ought to be. Weird.
I think mkimage is run as a host tool, so I'd dig into the build of that
on the host.
