2016-01-06cbfstool: correct add-master-header logic to match runtime expectationsAaron Durbin
The cbfs master header's offset and romsize fields are absolute values within the boot media proper. Therefore, when adding a master header provide the offset of the CBFS region one is operating on as well as the absolute end offset (romsize) to match expectations. Built with and without CBFS_SIZE != ROM_SIZE on x86 and ARM device. Manually inspected the master headers within the images to confirm proper caclulations.

For the purposes of maintaining integrity of a CBFS allow one to hash a CBFS over a given region. The hash consists of all file metadata and non-empty file data.

2016-01-06cbfstool: Adapt "cbfstool copy" to only use fmap regions.Patrick Georgi
These need to go together, so the commit became a bit larger than typial. - Add an option -R for the copy source fmap region. Use: cbfstool copy -r target-region -R source-region. - Don't generate a CBFS master header because for fmap regions, we assume that the region starts with a file header. Use cbfstool add-master-header to add it afterwards, if necessary. - Don't copy files of type "cbfs master header" (which are what cbfstool add-master-header creates) - Leave room for the master header pointer - Remove -D command line option as it's no longer used.

2015-12-12cbfstool: add ppc64 supportRonald G. Minnich
The constant for ppc64 is 'hotstuff'. For many reasons. Note that line 2894 of elf.h is not indented. This is because in the original the line begins with a space. Checkpatch rejects that. Checkpatch also rejects changing the space to a tab because that makes it more than 80 chars. I rejected breaking the line because it makes it even less readable. All the changes forced by checkpatch make the code less readable. Herman Hollerith would be proud. Change-Id: I21f049fe8c655a30f17dff694b8f42789ad9efb7 Signed-off-by: Ronald G.

2015-12-11build system: Switch to fmap based firmware layoutPatrick Georgi
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)
2015-12-09cbfstool: make top-aligned address work per-regionPatrick Georgi
The former interpretation sprung from the x86 way of doing things (assuming top-alignment to 4GB). Extend the mechanism to work with CBFS regions residing elsewhere. It's compatible with x86 because the default region there resides at the old location, so things fall in place. It also makes more complex layouts and non-x86 layouts work with negative base addresses.

2015-10-17cbfstool: Fix removing and adding file with same nameAaron Durbin
Currently, cbfstool regressed that removing a file from CBFS the space is marked as empty but the filename is still shown, preventing adding a file with the same name again. [1] ``` $ echo a > a $ echo b > b $ ./util/cbfstool/cbfstool test.rom create -m x86 -s 1024 Created CBFS (capacity = 920 bytes) $ ./util/cbfstool/cbfstool test.rom add -f a -n a -t raw $ ./util/cbfstool/cbfstool test.rom add -f b -n b -t raw $ cp test.rom test.rom.original $ ./util/cbfstool/cbfstool test.rom remove -n $ diff -up <(hexdump -C test.rom.original) <(hexdump -C test.rom) --- /dev/fd/63 2015-08-07 08:43:42.118430961 -0500 +++ /dev/fd/62 2015-08-07 08:43:42.114430961 -0500 @@ -1,4 +1,4 @@ -00000000 4c 41 52 43 48 49 56 45 00 00 00 02 00 00 00 50 |LARCHIVE.......P| +00000000 4c 41 52 43 48 49 56 45 00 00 00 02 ff ff ff ff |LARCHIVE........| 00000010 00 00 00 00 00 00 00 28 61 00 00 00 00 00 00 00 |.......(a.......| 00000020 00 00 00 00 00 00 00 00 61 0a ff ff ff ff ff ff |........a.......| 00000030 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| $ ./util/cbfstool/cbfstool test.rom add -f c -n c -t raw $ ./util/cbfstool/cbfstool test.rom print test.rom: 1 kB, bootblocksize 0, romsize 1024, offset 0x0 alignment: 64 bytes, architecture: x86 Name Offset Type Size c 0x0 raw 2 b 0x40 raw 2 (empty) 0x80 null 792 ``` So it is “deteled” as the type changed. But the name was not changed to match the *(empty)* heuristic. So also adapt the name when removing a file by writing a null byte to the beginning of the name, so that the heuristic works. (Though remove doesn't really clear contents.) ``` $ ./util/cbfstool/cbfstool test.rom remove -n c $ ./util/cbfstool/cbfstool test.rom print test.rom: 1 kB, bootblocksize 0, romsize 1024, offset 0x0 alignment: 64 bytes, architecture: x86 Name Offset Type Size (empty) 0x0 null 2 b 0x40 raw 2 (empty) 0x80 null 792 ``` [1] http://www.coreboot.org/pipermail/coreboot/2015-August/080201.html Change-Id: I033456ab10e3e1b402ac2374f3a887cefd3e5abf Signed-off-by: Aaron Durbin <adurbin@chromium.org> Signed-off-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-on: http://review.coreboot.org/11632 Tested-by: build bot (Jenkins) Tested-by: Raptor Engineering Automated Test Stand <noreply@raptorengineeringinc.com>

2015-10-02cbfstool: relocate FSP blobs on cbfstool addAaron Durbin
When adding an FSP blob relocate it to its final destination. This allows FSP to not be hard coded in the cbfs. In order for the include paths to work correctly w/ the edk 2 headers we need to supply a neutered ProcessorBind.h to match up with the tool environment such that one can get the UEFI Platform Initialization type definitions. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built glados and booted. Also added FSP with -b and manually adjusted location in fsp cache-as-ram. Booted as well.

2015-10-01cbfstool: Add support for hashes as file metadataPatrick Georgi
They allow optimizing a verification of a whole CBFS image by only dealing with the headers (assuming you choose to trust the hash algorithm(s)). The format allows for multiple hashes for a single file, and cbfstool can handle them, but right now it can't generate such headers. Loosely based on Sol's work in http://review.coreboot.org/#/c/10147/, but using the compatible file attribute format. vboot is now a hard dependency of the build process, but we import it into the tree for quite a while now.

That way code which uses printk() can than be mapped properly to verbosity of utility parameters.

2015-09-21cbfstool: make fmap search more strictPatrick Georgi
Since fmap doesn't come with a checksum, we resort to a number of heuristics to determine if a given location hosts an fmap (instead of another data structure that happens to store the fmap magic string at the right location). The version test is particularly effective against strings containing the magic (which either terminate with 0, or have some other ASCII data, but rarely a '\001' byte inside the string).

2015-09-21cbfstool: add new add-master-header commandPatrick Georgi
The command adds a new cbfs file, fills in the CBFS meta data in cbfs master header format, then points the master header pointer (which resides at the last 4 bytes of the CBFS region) to the data area of the new file. This can leak some space in CBFS if an old-style CBFS with native master header gets the treatment, because a new header is created and pointed at. flashmap based images have no such header, and the attempt to create a second file with the (hardcoded) name will fail.
