Please see these:

+ to generate the files, you need to run the configuration tool under
WinDOS. If you don't have access to that, just change the .h and .ldi
files by hand (ignore the .mlt file).

The sections are defined by the linker, try 'XXX-elf-ld --verbose'.
But if you are just adding a new platform, the architecture/variant
already defines the necessary sections (see the .ld file)
