This is a driver for accessing the EFI secret area via securityfs.
The EFI secret area is a memory area designated by the firmware for
confidential computing secret injection (for example for AMD SEV
guests). The driver exposes the secrets as files in
<securityfs>/secrets/coco. Files can be read and deleted (deleting
a file wipes the secret from memory).
To compile this driver as a module, choose M here.
The module will be called efi_secret.
