From 8a3592eec3501a55cdc1799987f18489db86c25a Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Wed, 16 Sep 2015 18:10:52 +0200 Subject: build system: Switch to fmap based firmware layout 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 Reviewed-on: https://review.coreboot.org/11692 Reviewed-by: Aaron Durbin Tested-by: build bot (Jenkins) --- util/cbfstool/default-x86.fmd | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 util/cbfstool/default-x86.fmd (limited to 'util/cbfstool/default-x86.fmd') diff --git a/util/cbfstool/default-x86.fmd b/util/cbfstool/default-x86.fmd new file mode 100644 index 0000000000..f344ab2086 --- /dev/null +++ b/util/cbfstool/default-x86.fmd @@ -0,0 +1,15 @@ +# layout for firmware residing at top of 4GB address space +# +-------------+ <-- 4GB - ROM_SIZE / start of flash +# | unspecified | +# +-------------+ <-- 4GB - BIOS_SIZE +# | FMAP | +# +-------------+ <-- 4GB - BIOS_SIZE + FMAP_SIZE +# | CBFS | +# +-------------+ <-- 4GB / end of flash + +FLASH@##ROM_BASE## ##ROM_SIZE## { + BIOS@##BIOS_BASE## ##BIOS_SIZE## { + FMAP@##FMAP_BASE## ##FMAP_SIZE## + COREBOOT(CBFS)@##CBFS_BASE## ##CBFS_SIZE## + } +} -- cgit v1.2.3
