Until now, LinuxBIOS has used elf for the payload. There are many problems
this, not least being the inefficiency -- the ELF has to be decompressed to
memory and then the segments have to be copied. Plus, lar can't see the segments
in the elf -- to see all segments, you have to extract the elf and run readelf on it.
There are problems with collisions of the decompressed ELF location in memory
and the segment locations in memory.
Finally, validation of the ELF is done at run time, once you have flashed the
FLASH and rebooted the machine. Boot time is really not the time you want to find
out your ELF payload is broken.
With this option, LinuxBIOS will direct lar to break each elf segment into a LAR
entry. ELF will not be used at all. Note that (for now) LinuxBIOS is backward
compatible -- if you put an ELF payload in, LinuxBIOS can still parse it. We hope
to remove ELF entirely in the future.
