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
