Argument: uintptr_t
Argument: uintptr_t ep, unsigned int client_mode
Return: int
This function validates the address of client entry points provided for both
event registration and *Complete and Resume* |SDEI| calls. The function
takes one argument, which is the address of the handler the |SDEI| client
requested to register. The function must return ``0`` for successful validation,
or ``-1`` upon failure.
This function validates the entry point address of the event handler provided by
the client for both event registration and *Complete and Resume* |SDEI| calls.
The function ensures that the address is valid in the client translation regime.
The second argument is the exception level that the client is executing in. It
can be Non-Secure EL1 or Non-Secure EL2.
The function must return ``0`` for successful validation, or ``-1`` upon failure.
The default implementation always returns ``0``. On Arm platforms, this function
is implemented to translate the entry point to physical address, and further to
ensure that the address is located in Non-secure DRAM.
translates the entry point address within the client translation regime and
further ensures that the resulting physical address is located in Non-secure
DRAM.
