DESCRIPTION
This script defines the memory location of the various sections that make up
a Zephyr Kernel image. This file is used by the linker.

This script places the various sections of the image according to what features
are enabled by the kernel's configuration options.

For a build that does not use the execute in place (XIP) feature, the script
generates an image suitable for loading into and executing from RAM by placing
all the sections adjacent to each other.  There is also no separate load
address for the DATA section which means it doesn't have to be copied into RAM.

For builds using XIP, there is a different load memory address (LMA) and
virtual memory address (VMA) for the DATA section.  In this case the DATA
section is copied into RAM at runtime.

When building an XIP image the data section is placed into ROM.  In this case,
the LMA is set to __data_rom_start so the data section is concatenated at the
end of the RODATA section.  At runtime, the DATA section is copied into the RAM
region so it can be accessed with read and write permission.

Most symbols defined in the sections below are subject to be referenced in the
Zephyr Kernel image. If a symbol is used but not defined the linker will emit an
undefined symbol error.

Please do not change the order of the section as the nanokernel expects this
order when programming the MMU.
