The UAVObject initcall list is now automatically
generated at link time based on the exact set of
UAVObjects linked into the firmware image.
This will allow any subset of UAVObjects to be
used in any firmware image.
The uavobj_initcall() macro automatically adds the
marked function's address into the .initcalluavobj.init
ELF section.
The UAVObjectsInitializeAll() function now simply
iterates over the functions listed in the
.initcalluavobj.init section and calls them.
You can see the contents of this section in the ELF file
like this:
./tools/arm-2009q3/bin/arm-none-eabi-objdump \
--syms -j .initcalluavobj.init \
./build/openpilot/OpenPilot.elf
This is fundamentally the same mechanism that the Linux
kernel uses to initialize the specific set of components
that the user has selected in their kernel configuration.
