2016-01-28util/cbfstool: add 'compact' commandAaron Durbin
While assembling CBFS images within the RW slots on Chrome OS machines the current approach is to 'cbfstool copy' from the RO CBFS to each RW CBFS. Additional fixups are required such as removing unneeded files from the RW CBFS (e.g. verstage) as well as removing and adding back files with the proper arguments (FSP relocation as well as romstage XIP relocation). This ends up leaving holes in the RW CBFS. To speed up RW CBFS slot hashing it's beneficial to pack all non-empty files together at the beginning of the CBFS. Therefore, provide the 'compact' command which bubbles all the empty entries to the end of the CBFS.

2015-05-13cbfstool: Support top-aligned addresses for new-format imagesSol Boucher
The cbfstool handling of new-style FMAP-driven "partitioned" images originally disallowed the use of x86-style top-aligned addresses with the add.* and layout actions because it wasn't obvious how they should work, especially since the normal addressing is done relative to each individual region for these types of images. Not surprisingly, however, the x86 portions of the build system make copious use of top-aligned addresses, so this allows their use with new images and specifies their behavior as being relative to the *image* end---not the region end---just as it is for legacy images.

2015-05-13cbfstool: New image format w/ required FMAP and w/o CBFS master headerSol Boucher
These new-style firmware images use the FMAP of the root of knowledge about their layout, which allows them to have sections containing raw data whose offset and size can easily be determined at runtime or when modifying or flashing the image. Furthermore, they can even have multiple CBFSes, each of which occupies a different FMAP region. It is assumed that the first entry of each CBFS, including the primary one, will be located right at the start of its region. This means that the bootblock needs to be moved into its own FMAP region, but makes the CBFS master header obsolete because, with the exception of the version and alignment, all its fields are redundant once its CBFS has an entry in the FMAP. The version code will be addressed in a future commit before the new format comes into use, while the alignment will just be defined to 64 bytes in both cbfstool and coreboot itself, since there's almost no reason to ever change it in practice. The version code field and all necessary coreboot changes will come separately. BUG=chromium:470407 TEST=Build panther and nyan_big coreboot.rom and image.bin images with and without this patch, diff their hexdumps, and note that no locations differ except for those that do between subsequent builds of the same codebase. Try working with new-style images: use fmaptool to produce an FMAP section from an fmd file having raw sections and multiple CBFSes, pass the resulting file to cbfstool create -M -F, then try printing its layout and CBFSes' contents, add and remove CBFS files, and read and write raw sections.

2015-05-08cbfstool: Restructure around support for reading/writing portions of filesSol Boucher
The buffer API that cbfstool uses to read and write files only directly supports one-shot operations on whole files. This adds an intermediate partitioned_file module that sits on top of the buffer system and has an awareness of FMAP entries. It provides an easy way to get a buffer for an individual region of a larger image file based on FMAP section name, as well as incrementally write those smaller buffers back to the backing file at the appropriate offset. The module has two distinct modes of operation: - For new images whose layout is described exclusively by an FMAP section, all the aforementioned functionality will be available. - For images in the current format, where the CBFS master header serves as the root of knowledge of the image's size and layout, the module falls back to a legacy operation mode, where it only allows manipulation of the entire image as one unit, but exposes this support through the same interface by mapping the region named SECTION_NAME_PRIMARY_CBFS ("COREBOOT") to the whole file. The tool is presently only ported onto the new module running in legacy mode: higher-level support for true "partitioned" images will be forthcoming. However, as part of this change, the crusty cbfs_image_from_file() and cbfs_image_write_file() abstractions are removed and replaced with a single cbfs_image function, cbfs_image_from_buffer(), as well as centralized image reading/writing directly in cbfstool's main() function. This reduces the boilerplate required to implement each new action, makes the create action much more similar to the others, and will make implementing additional actions and adding in support for the new format much easier.

2015-04-18cbfstool: add a command to duplicate a cbfs instanceVadim Bendebury
The new command allows to create a file where the original CBFS image is duplicated at a different offset. The required options of the new command are -D, the offset where the copy CBFS header is placed, and -s, the size of the new CBFS copy. When a CBFS is copied, the bootblock area of the source CBFS is ignored, as well as empty and deleted files in the source CBFS. The size of the destination CBFS is calculated as the rombase size of the source CBFS less the bootblock size. The copy instance can be created in the image only above the original, which rules out the use of this new command for x86 images. If necessary, this limitation could be addressed later. As with other cbfstool commands, unless explicitly specified the lowest CBFS instance in the image is considered the source. If necessary, the user can specify the source CBFS using the -H option.

2015-04-18cbfstool: allow user to explicitly specify header locationVadim Bendebury
There potentially could be multiple CBFS instances present in the firmware image. cbfstool should be able to operate on any of them, not just the first one present. To accomplish that, allow all CBFS commands to accept the -H parameter (which specifies the exact CBFS header location in the image). If this parameter is specified, the image is not searched for the CBFS header, only the specified location is checked for validity, If the location is valid, it is considered to be the CBFS header, if not - the tool exits with an error status. Note, that default behavior of the tool does not change.

2014-02-11cbfstool: Deserialize CBFS master header when reading imageAlexandru Gagniuc
Rather than using [hn]to[nh] whenever accessing a member of the CBFS header, deserialize the header when opening the CBFS image. The header is no longer a pointer inside the CBFS buffer, but a separate struct, a copy of the original header in a host-friendly format. This kills more of the ntohl usage.

This change adds a header serialization function. Programmers can thus just set up a header as needed, without worrying about forgetting if and how to use the [hn]to[hn]* functions. In the long term, we will work to remove swab.h, i.e. we need to get to the point where programmers don't have to try to remember [hn]to[nh]* and where it goes. To date, even the best programmers we have have made an error with those functions, and those errors have persisted for 6 or 7 years now. It's very easy to make that mistake.
