The libs directory may contain libesp_rom.a (or any other static library) meant to patch ROM functions.
Additionally you can have a add_rwtext file which adds to the .rwtext section.
Remember the linker scripts usually define the ROM functions weakly which means we can patch them.
Patches for all chips should originate from one ESP-IDF version only and that should be documented in the crate's README.md.
