2015-05-26cbfstool: Make update-fit action work on new-style imagesSol Boucher
Because new images place the bootblock in a separate region from the primary CBFS, performing an update-fit operation requires reading an additional section and choosing a different destination for the write based on the image type. Since other actions are not affected by these requirements, the logic for the optional read and all writing is implemented in the cbfs_update_fit() function itself, rather than relying on the main() function for writing as the other actions do.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

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.

2015-05-08fmaptool: Add listing of annotated CBFS sections and generate headerSol Boucher
The fmd compiler now processes "(CBFS)" annotations, distilling them into a comma-separated list of the names of sections containing CBFSes. This list is the only thing printed to standard output to enable easy capture and machine consumption by other tools. Additionally, the ability to generate a tiny header with a define for the primary CBFS's size is implemented and can be requested via a new command-line switch. Here's an example of how to use the new features: $ ./fmaptool -h layout.h layout_arm_8192.fmd layout.fmap 2>/dev/null FW_MAIN_A,FW_MAIN_B,COREBOOT The hypothetical fmd file contains three sections annotated as (CBFS), the names of which are printed to standard output. As before, a binary FMAP file named layout.fmap is created; however, because the command was invoked with -h, a header #define ing the offset of its FMAP section (i.e. where it will be relative to the base of flash once the boot image is assembled) is also generated. BUG=chromium:470407 TEST=Verify that fmd files without a "COREBOOT" section or with one that isn't annotated as "(CBFS)" are not accepted.

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. BUG=chromium:470407 TEST=Build panther and nyan_big coreboot.rom images with and without this patch and diff their hexdumps.

2015-05-08cbfstool: Simplify the common buffer_splice() function's interfaceSol Boucher
Previously, this function allowed one to pass a size of 0 in order to indicate that the entire buffer should be copied. However, the semantics of calling it this way were non-obvious: The desired behavior was clear when the offset was also 0, but what was the expected outcome when the offset was nonzero, since carrying over the original size in this case would be an error? In fact, it turns out that it always ignored the provided offset when the size was zero. This commit eliminates all special handling of 0; thus, the resulting buffer is exactly as large as requested, even if it's degenerate. Since the only consumer that actually called the function with a size of 0 was buffer_clone(), no other files required changes.

2015-05-08fmaptool: Introduce the fmd ("flashmap descriptor") language and compilerSol Boucher
This adds a compiler for a language whose textual representation of flashmap regions will be used to describe the layout of flash chips that contain more than just a single CBFS. Direct integration with cbfstool (via a new command-line switch for the create action) is forthcoming but will be added separately.

2015-05-08cbfstool: Make the add action choose an aligned entries capacitySol Boucher
This fixes an inconsistency between `cbfstool create` and `cbfstool add` that was resulting in confusing claims about the amount of free space at the end of a CBFS. Calls to `cbfstool add` check whether a file fits under a given empty file entry by testing whether it would collide with the beginning of the *subsequent* file header; thus, if a file's end is unaligned, its reported size will not match the actual available capacity. Although deleted entries always end on an alignment boundary because `cbfstool remove` expands them to fill the available space, `cbfstool create` doesn't necessarily size a new entries region to result in an empty entry with an aligned end. This problem never resulted in clobbering important data because cbfstool would blindly reserve 64B (or the selected alignment) of free space immediately after the all-inclusive empty file entry. This change alters the way this reservation is reported: only the overhang past the alignment is used as hidden padding, and the empty entry's capacity is always reported such that it ends at an aligned address. Much of the time that went into this patch was spent building trust in the trickery cbfstool employs to avoid explicitly tracking the image's total capacity for entries, so below are two proofs of correctness to save others time and discourage inadvertent breakage: OBSERVATION (A): A check in cbfs_image_create() guarantees that an aligned CBFS empty file header is small enough that it won't cross another aligned address. OBSERVATION (B): In cbfs_image_create(), the initial empty entry is sized such that its contents end on an aligned address. THM. 1: Placing a new file within an empty entry located below an existing file entry will never leave an aligned flash address containing neither the beginning of a file header nor part of a file. We can prove this by contradiction: assume a newly-added file neither fills to the end of the preexisting empty entry nor leaves room for another aligned empty header after it. Then the first aligned address after the end of the newly-inserted file... - CASE 1: ...already contains a preexisting file entry header. + Then that address contains a file header. - CASE 2: ...does not already house a file entry header. + Then because CBFS content doesn't fall outside headers, the area between there and the *next* aligned address after that is unused. + By (A), we can fit a file header without clobbering anything. + Then that address now contains a file header. THM. 2: Placing a new file in an empty entry at the very end of the image such that it fits, but leaves no room for a final header, is guaranteed not to change the total amount of space for entries, even if that new file is later removed from the CBFS. Again, we use contradiction: assume that creating such a file causes a permanent... - CASE 1: ...increase in the amount of available space. + Then the combination of the inserted file, its header, and any padding must have exceeded the empty entry in size enough for it to cross at least one additional aligned address, since aligned addresses are how the limit on an entry's capacity is determined. + But adding the file couldn't have caused us to write past any further aligned addresses because they are the boundary's used when verifying that sufficient capacity exists; furthermore, by (B), no entry can ever terminate beyond where the initial empty entry did when the CBFS was first created. + Then the creation of the file did not result in a space increase. - CASE 2: ...decrease in the amount of available space. + Then the end of the new file entry crosses at least one fewer aligned address than did the empty file entry. + Then by (A), there is room to place a new file entry that describes the remaining available space at the first available aligned address. + Then there is now a new record showing the same amount of available space. + Then the creation of the file did not result in a space decrease.
