We can use same U-Boot binary compiled using qemu-riscv64_smode_defconfig on QEMU virt machine and QEMU spike machine. To achieve this, we need HTIF console support for U-Boot QEMU RISC-V board hence this series.
To test this series with latest OpenSBI, we can use the following command: qemu-system-riscv64 -M spike -m 256M -display none -serial stdio \ -bios opensbi/build/platform/generic/firmware/fw_jump.bin -kernel \
I think you forgot to mention this needs an updated QEMU too, due to plain binary is now used for spike?
Ahh, yes. I should have provided the link to the QEMU spike machine patch.
