Sorry, I'm not quite sure how to read that... did you literally mean that the cbfstool commands (or something equivalent) would be *in* the .fmd file? That is certainly not what I meant. Instead, I was suggesting to use well-known CBFS "categories" and have another part of the system (e.g. the Makefiles) map files to those. For example when something (a mainboard, an SoC, etc.) declares a file, it would declare that this file belongs to the "pre-boot-split CBFS" category or the "post-boot-split CBFS" category (or for all I care you could also bind them directly to romstage/ramstage/etc. which is I think closer to what you were proposing). Then the part deciding the boot scheme ("vboot" and "traditional coreboot" for now) would know that all "pre-boot-split" files would belong into the well-known CBFS FMAP sections "FALLBACK" and "NORMAL" for traditional coreboot, whereas "post-boot-split" would only go into "NORMAL" (and the vboot version would instead know how to bind those categories to its RO/RW_A/RW_B sections). The .fmd file should *only* define the layout, and all the individual platform pieces that need to add files should *only* declare something abstract about in which context those files are used. Then something else (which is deciding the general boot method) should define how to bind those two together. -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
