Let the sbi command display:
* machine vendor ID * machine architecture ID * machine implementation ID
With this patch the output for the HiFive Unmatched looks like
=> sbi SBI 0.3 OpenSBI 0.9 Machine: Vendor ID 489 Architecture ID 8000000000000007 Implementation ID 20181004 Extensions: sbi_set_timer sbi_console_putchar sbi_console_getchar sbi_clear_ipi sbi_send_ipi sbi_remote_fence_i sbi_remote_sfence_vma sbi_remote_sfence_vma_asid sbi_shutdown SBI Base Functionality Timer Extension IPI Extension RFENCE Extension Hart State Management Extension System Reset Extension
