| # Attempts to add entropy while running RW firmware and verifies that it fails. |
| # Adds entropy from RO firmware and verifies that rollback block ID increments |
| # by one. Then adds entropy with reset (double write) and verifies block ID |
| # incremented by two. Finally, reboots back to RW. |
