At present the 32-bit OpenSBI generic firmware image does not boot on Spike, only 64-bit image can. This is due to the HTIF emulation does not implement the proxy syscall interface which is required for the 32-bit HTIF console output.
An OpenSBI bug fix [1] is also needed when booting the plain binary image. With this series plus the above OpenSBI fix, both 32-bit OpenSBI BIN & ELF images can boot on QEMU 'spike' machine.
