Well... I was working the assumption an array of pointers couldn't possibly get hosed. That's about all I got for that. ;) As for decorating the structures it's just sort of a pain in that you need to match alignment of the symbol in the linker script and the structure declaration -- for every object that we place like this in the linker scripts. Definitely doable though. Something to keep in one's back pocket. -Aaron -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
