| 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. |
