There definitely seems to be some WDT still running:

10 seconds after first power-on it resets
- Do we need to ACK/set a signal?
On second boot, FSP-S init fails (0x40000003; FSP_STATUS_GLOBAL_RESET_REQUIRED_3) and it triggers a global reset
Then on the 3rd boot it finally reaches payload

That fact that it's always 10 seconds makes me think that a press-and-release is triggering some PWRSW WDT (like how holding for 10s should trigger power off).

Issue is "DACC" feature. A single note about it exists in the manual: "Auto clear CMOS when system boot improperly". Can be addressed for now by removing the JP1_57 jumper.
