 * This structure represents the superset of information that can be passed to

 * populated only if BL2 detects its presence. A pointer to a structure of this
 * type should be passed in X0 to BL31's cold boot entrypoint.
 *
 * Use of this structure and the X0 parameter is not mandatory: the BL31
 * platform code can use other mechanisms to provide the necessary information
 * about BL32 and BL33 to the common and SPD code.
 *
 * BL31 image information is mandatory if this structure is used. If either of
 * the optional BL32 and BL33 image information is not provided, this is
 * indicated by the respective image_info pointers being zero.
