This seems to be new, what's the justification?
Seems to be a run-time replacement of:

The core RTAS support code and its clients perform two types of lookup
for RTAS firmware function information.
First, mapping a known function name to a token. The typical use case
invokes rtas_token() to retrieve the token value to pass to
rtas_call(). rtas_token() relies on of_get_property(), wh
