We still add a master header for compatibility purposes, and the default layouts don't cover anything non-coreboot (eg. IFD regions) yet. The default layouts can be overridden by specifying an fmd file, from which the fmap is generated. Future work: - map IFD regions to fmap regions - non-x86: build minimalistic trampolines that jump into the first cbfs file, so the bootblock can be part of CBFS instead of reserving a whole 64K for it. - teach coreboot's cbfs code to work without the master header - teach coreboot's cbfs code to work on different fmap regions Change-Id: Id1085dcd5107cf0e02e8dc1e77dc0dd9497a819c Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: https://review.coreboot.org/11692 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins)
