23 This document describes the secure world FWU design. It is beyond its scope to
24 describe how normal world FWU images should operate. To implement normal world
33 some parts of FWU to be implemented in other secure and normal world images.
42    -  Context switching between the normal and secure world during the FWU
45 -  Other secure world FWU images handle platform initialization required by
47 -  Normal world FWU images handle loading of firmware images from external
79 -  Executable or non-executable image. This indicates whether the normal world
80    is permitted to request execution of a secure world FWU image (after
81    authentication). Secure world certificates and non-AP images are examples

303 implementation only supports normal world callers initiating execution of a
304 secure world image.
306 BL1 saves the normal world caller's context, sets the secure image state to

325 This SMC resumes execution in the other security world while there is a secure
328 For normal world callers, BL1 sets the previously interrupted secure image state
329 to EXECUTED. For secure world callers, BL1 sets the previously executing secure
330 image state to INTERRUPTED. In either case, BL1 saves the calling world's
331 context, restores the resuming world's context and returns from exception into
332 the resuming world. If the call is successful then the caller provided
333 ``image_param`` is returned to the resumed world, otherwise an error code is
