One might want to select the symbols to be relocated inside a file or a library. To do this, one can use the FILTER argument of zephyr_code_relocate which must contain a regular expression of the section names to be selected for relocation. The test_function_in_sram2 test case in `tests/application_development/code_relocation` has been updated to verify that only one function `function_in_sram()` is relocated to ram and that the function `function_not_relocated()` is not being relocated when using relocation filter.
