2. We added a special section (resource table) that is interpreted as part
of the loading process. The tool that generates our simple format just
recognizes a named section (".resource_table"), so perhaps that could be
done with the PIL ELF loader.
I hope that DT will completely replace that "resource table" section
eventually. We still need to try it out (as soon as DT materializes on
ARM/pandaboard) and see how it all fits together, but in general it
looks like DT could provide all the necessary static resource
configuration, and then we just need to expose it to the remote
processor.
I'm not sure I see the benefit to pulling the resource information out
of the firmware image.  The resource information is a description of
what resources the firmware requires to work properly (it needs
certain amounts of working memory, timers, peripheral interfaces like
i2c to control camera hw, etc), which will be specific to a given
firmware build.  Pulling that information out into another place adds
new ways for things to break as the firmware and its resource
requirements are now separate and could get out of sync, etc.
