In current versions of spike, the config string is not available anymore, because RISC-V is moving toward OpenFirmware-derived device trees (either in FDT or text format). Using query_config_string leads to a crash in these versions of spike. With this commit and If0bea4bf52d ("riscv: Update register address"), coreboot reaches the romstage again, on spike.
