| This option should be selected if the platform requires special handling |

| necessary on Intel platforms, as directly powering off before memory |
| initialization is typically not supported by the chipset. |
| |
| Selecting this option indicates that the platform implements the |
| `platform_do_early_poweroff()` function, which performs the |
| necessary hardware operations to initiate an early power off sequence. |
| This might involve configuring hardware registers, sending commands to |
| power management controllers, or other platform-specific operations. |
