As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

Intel ADSP CAVS Code relocation
###############################
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.
Building and Running
********************
This application can be built and executed as follows:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: intel_adsp_cavs25
:goals: build
