      8	  This is a driver for accessing the EFI secret area via securityfs.
      9	  The EFI secret area is a memory area designated by the firmware for
     10	  confidential computing secret injection (for example for AMD SEV
     11	  guests).  The driver exposes the secrets as files in
     12	  <securityfs>/secrets/coco.  Files can be read and deleted (deleting
     13	  a file wipes the secret from memory).

     15	  To compile this driver as a module, choose M here.
     16	  The module will be called efi_secret.
