On some platforms, such as imx8x, an authenticated message is necessary to advance the life cycle to EOL. Prepare the EOL SLC API's to receive such a message. For imx8x, knowing the length of the message is not strictly necessary as it will just relay this message to the SCU and eventually the SECO. For future purposes, a length argument might be necessary. Therefore, add it right away.
The SECO is able to provide additional events which may contain things such as extended error codes to previous RPC calls. It's quite rough on the edges as the documentation states that it has a fixed number of events it can store and once the maximum number of events have been reached, it will no longer store any more events. The event codes are still useful in some cases for debugging purposes. Add support for reading the last recorded event.
Some RPC calls, such as return_lifecycle takes an address as argument. These addresses must be readable from the SCU's point of view. Add a mapping to "Secure RAM" to be able to send authenticated messages to the SCU.
Add support for advancing to EOL/Return Lifecycle
Some platforms require a authentication message in order to advance to EOL lifecycle. Add an optional argument to support this.
If the SECO is unable to provide the current life cycle, take the safe route and panic as the result is used to determine whether or not authentication is needed for command mode.
