It would be preferable to disable only after confirmation, to avoid case where CSME has to be re-enabled after update is canceled. |
Move disabling CSME from BIOS validation to main app update logic. This allows users to accept updating before disabling, or cancel without disabling. Signed-off-by: Tim Crawford <tcrawford@system76.com>

QA can test in updates to firmware and firmware-open, this looks good on my meer9. |

CSME must be disabled or in read-only mode to before writing to the CSME region of SPI flash. CSME global reset (as opposed to PCH reset) must be used to ensure system fully resets. Otherwise, CSME may break and cause boot failures.
