If a particular project needs to add additional data to the
binary image, in most cases the entire linker script needs to
forked into the project space, causing maintenance issues if
the main linker script is changed.
Now we add some Kconfig options to allow a project to specify
some additional linker scripts which get included by the main
one in a few key areas:
1) In the definition to the 'rodata' section, which can allow
additional data to be included in this ROM section.
2) In the definition to the 'datas' section, which allows
additional data to be included in this RAM section.
3) Arbitrary additional sections to be included at the end of
the binary.
For 1 and 2, this is useful to include data generated outside of
the normal C compilation, such as data structures that are created
by special build tools.
3 is useful for including arbitrary binary blobs inside the final
image, such as for peripheral or co-processor firmware.
