ACPI_S3 resume mechanism in coreboot

[Yoshinoya]

Hi, Kyosti:
I ask for help.
Is there any document introducing acpi s3 resume mechanism in coreboot ?

I am familiar with uefi bios, and there is boot script concept in uefi code.
Buf I could not find any boot script code implemented in coreboot.

For some early coreboot code(such as 2022 ver), there is an amd porting boot script infrastructure code in coreboot.
Buf now, I could not find them in 2024 ver code package.

Thanks
