Documentation of ROM functions for deep sleep wake stub

[stefaanv]

According to official documentation, deep sleep wake stub code can only call functions implemented in ROM or loaded into RTC Fast Memory.
How/where can I find which functions have been implemented in ROM ?

A pure guess on my part ... but it might be the functions with the signatures described here:
