.. zephyr:code-sample:: intel_adsp_code_relocation
   :name: Code relocation

   Relocate code using custom linker script.

Overview
********

A simple sample that shows code relocation working for Intel ADSP CAVS
boards (v18 and v25). The interesting bit is the custom linker file.
As rimage (the tool used to sign the image) mandates that elf files
sections TEXT, DATA and BSS be contiguous, some work is done in the
linker script to ensure that.
