@ -1087,13 +1087,15 @@ The default implementation spins forever.
Argument : uintptr_t mem_base, unsigned int mem_size,
unsigned int flags
Return : void
Return : int
BL1 calls this function while handling FWU copy and authenticate SMCs. The
platform must ensure that the provided `mem_base` and `mem_size` are mapped into
BL1, and that this memory corresponds to either a secure or non-secure memory
region as indicated by the security state of the `flags` argument.
This function must return 0 on success, a non-null error code otherwise.
The default implementation of this function asserts therefore platforms must
override it when using the FWU feature.
