* enum transfer_kind - How to send an fd to Trusty
- * @TRUSTY_SHARE: Memory will be accessible by Linux and Trusty. On ARM it will
- * be mapped as nonsecure. Suitable for shared memory. The paired
- * fd must be a "memfd".
- * @TRUSTY_LEND: Memory will be accessible only to Trusty. On ARM it will be
- * transitioned to "Secure" memory if Trusty is in TrustZone.
- * This transfer kind is suitable for donating video buffers or
- * other similar resources. The paired fd may need to come from a
- * platform-specific allocator for memory that may be
- * transitioned to "Secure".
+ * @TRUSTY_SHARE: Memory will be accessible by Linux and Trusty. On ARM it

+ * @TRUSTY_SEND_SECURE: Send memory that is already "Secure". Memory will be

* Describes how the user would like the resource in question to be sent to
