[External Email] Do not click links or attachments unless you recognize the sender and know the content is safe
Provide a command to display information about the SBI implementation.
The output might look like:
=> sbi SBI 0.2 OpenSBI 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
The command can be used to construct a unit test checking that the communication with the SEE is working.
