10  * DOC: efi_secret: Allow reading EFI confidential computing (coco) secret area
15  * In it, a file is created for each secret entry.  The name of each such file
16  * is the GUID of the secret entry, and its content is the secret data.
41  * Structure of the EFI secret area
46  *       0       16  Secret table header GUID (must be 1e74f542-71dd-4d66-963e-ef4287ff173b)
47  *      16        4  Length of bytes of the entire secret area
49  *      20       16  First secret entry's GUID
50  *      36        4  First secret entry's length in bytes (= 16 + 4 + x)
51  *      40        x  First secret entry's data
53  *    40+x       16  Second secret entry's GUID

55  *    60+x        y  Second secret entry's data
59  * The GUID of each secret entry designates the usage of the secret data.
63  * struct secret_header - Header of entire secret area; this should be followed
66  * @len:	Length in bytes of entire secret area, including header
74  * struct secret_entry - Holds one secret entry
75  * @guid:	Secret-specific GUID (or NULL_GUID if this secret entry was deleted)
76  * @len:	Length of secret entry, including its guid and len fields
77  * @data:	The secret data (full of zeros if this secret entry was deleted)
110  * actually written back to memory, to clear out the secret.
