Description
Use this option to reserve a place in ROM to be filled by some other tool, for example, a checksum calculated by ielftool. Each use of this linker option results in a section with the specified name, size, and alignment. The symbol can be used by your application to refer to the section.
Note
Like any other section, sections created by the ‑‑place_holder option will only be included in your application if the section appears to be needed. The ‑‑keep linker option, or the keep linker directive can be used for forcing such section to be included.
