rtoc pointer

Morning,

I was wondering if its possible of converting a virtual address like an elf file's entry point into a physical address or if not is it possible to locate where in the elf's .text file is the entry point is physically located?

The reason I ask is because is because im practicing reversing my own ppc code and I want to understand how to locate the TOC pointer by hand.

Using google I was able to locate that the initial rtoc pointer is pulled from the function descriptor pointed at by the e_entry fild in the ELF header.
