Even with -smp 1 you will see the same errors. The problem is because
there is nothing to run after OpenSBI jumps to the next stage.
If you load a kernel you will not see the error messages.

Title:
RISC-V 64, CPUs do ilegal 0x00 write with SMP
Status in QEMU:
Invalid
Bug description:
When QEMU is runt like this:
qemu-system-riscv64 -d unimp,guest_errors -smp 8
Other harts will do a illegal write on address 0x00.
This could be mostly (i think) because the initial assembly code is
only loaded on the first hart and the others do a mess because there
is no code to execute.
