| This test starts with RO normal mode and enables EC write protect. Software sync |
| supposed to write protect the entire EC flash, so we expect the following |
| write protect flags: |
| - wp_gpio_asserted |
| - ro_at_boot |
| - ro_now |
| - all_now |
| These flags are checked under following situations: |
| - Cold reset. RO normal. |
| - Cold reset. Two stop. |
| - Cold reset by ectool. Two stop. |
| At the end of the test, write protect is deactivated and firmware is restored to |
| RO normal mode. |
