RISC-V: crash in riscv_get_time()

Hello Rick, hello Bin,

when I run qemu-riscv64_defconfig using

qemu-system-riscv64 -machine virt -m 1G -nographic \ -bios u-boot \ -device virtio-net-device,netdev=net0 \ -netdev user,id=net0,tftp=tftp

a crash occurs in riscv_get_time() when executing readq().

$ qemu-system-riscv64 --version QEMU emulator version 5.0.0 (Debian 1:5.0-13)

Looking at doc/board/emulation/qemu-riscv.rst this should work.

Is there something missing in the documentation?

Best regards

Heinrich
