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.

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. Ensure that no differences occur at different locations from the diffs between subsequent builds of an identical source tree. Then flash a full new build onto nyan_big and watch it boot normally.

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.

2015-05-08cbfstool: 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.

This enables more warnings on the cbfstool codebase and fixes the issues that surface as a result. A memory leak that used to occur when compressing files with lzma is also found and fixed. Finally, there are several fixes for the Makefile: - Its autodependencies used to be broken because the target for the .dependencies file was misnamed; this meant that Make didn't know how to rebuild the file, and so would silently skip the step of updating it before including it. - The ability to build to a custom output directory by defining the obj variable had bitrotted. - The default value of the obj variable was causing implicit rules not to apply when specifying a file as a target without providing a custom value for obj. - Add a distclean target for removing the .dependencies file.

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.

2015-04-14CBFS: Automate ROM image layout and remove hardcoded offsetsJulius Werner
Non-x86 boards currently need to hardcode the position of their CBFS master header in a Kconfig. This is very brittle because it is usually put in between the bootblock and the first CBFS entry, without any checks to guarantee that it won't overlap either of those. It is not fun to debug random failures that move and disappear with tiny alignment changes because someone decided to write "ORBC1112" over some part of your data section (in a way that is not visible in the symbolized .elf binaries, only in the final image). This patch seeks to prevent those issues and reduce the need for manual configuration by making the image layout a completely automated part of cbfstool. Since automated placement of the CBFS header means we can no longer hardcode its position into coreboot, this patch takes the existing x86 solution of placing a pointer to the header at the very end of the CBFS-managed section of the ROM and generalizes it to all architectures. This is now even possible with the read-only/read-write split in ChromeOS, since coreboot knows how large that section is from the CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be changed on systems that place other data next to coreboot/CBFS in ROM). Also adds a feature to cbfstool that makes the -B (bootblock file name) argument on image creation optional, since we have recently found valid use cases for CBFS images that are not the first boot medium of the device (instead opened by an earlier bootloader that can already interpret CBFS) and therefore don't really need a bootblock.

2014-10-28cbfstool: If compression fails, warn and use the uncompressed data.Gabe Black
The LZMA compression algorithm, currently the only one available, will fail if you ask it to write more data to the output than you've given it space for. The code that calls into LZMA allocates an output buffer the same size as the input, so if compression increases the size of the output the call will fail. The caller(s) were written to assume that the call succeeded and check the returned length to see if the size would have increased, but that will never happen with LZMA. Rather than try to rework the LZMA library to dynamically resize the output buffer or try to guess what the maximal size the data could expand to is, this change makes the caller simply print a warning and disable compression if the call failed for some reason. This may lead to images that are larger than necessary if compression fails for some other reason and the user doesn't notice, but since compression errors were ignored entirely until very recently that will hopefully not be a problem in practice, and we should be guaranteed to at least produce a correct image.

This is currently happening for a segment of depthcharge which is triggering a failure in LZMA.

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

2014-09-04cbfstool:linux_trampoline: config CS and DS segment descriptorsCurt Brune
The Linux trampoline code does not set up the segment descriptors for __BOOT_CS and __BOOT_DS as described in the Linux kernel documentation: ... a GDT must be loaded with the descriptors for selectors __BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat segment; __BOOT_CS must have execute/read permission, and __BOOT_DS must have read/write permission; This is not a problem when launching a Linux payload from coreboot, as coreboot configures the segment descriptors at selectors 0x10 and 0x18. Coreboot configures these selectors in the ramstage to match what the Linux kernel expects (see coreboot/src/arch/x86/lib/c_start.S). When the cbfs payload is launched in other environments, SeaBIOS for example, the segment descriptors are configured differently and the cbfs Linux payload does not work. If the cbfs Linux payload is to be used in multiple environments should the trampoline needs to take care of the descriptors that Linux requires. This patch updates the Linux trampoline code to configure the 4G flat descriptors that Linux expects. The configuration is borrowed from the descriptor configs in coreboot/src/arch/x86/lib/c_start.S for selectors 0x10 and 0x18. The linux_trampoline code is slightly refractored by defining the trampoline entry address, 0x40000, as TRAMPOLINE_ENTRY_LOC. This definition is moved into a separate header file, linux_trampoline.h. This header file is now included by both the trampoline assembly language code and the trampoline loader C code. The trampoline assembly language code can now use TRAMPOLINE_ENTRY_LOC as scratch space for the sgdt CPU instruction. Testing Done: Verified the Linux payload is booted correctly in the following environments: 1. Coreboot -> Linux Payload 2. Coreboot -> SeaBIOS -> Linux Payload: (previously did not work) Change-Id: I888f74ff43073a6b7318f6713a8d4ecb804c0162 Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Reviewed-on: http://review.coreboot.org/6796 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.

2014-08-27rmodtool: correct final memory size calculationAaron Durbin
Apparently when I originally wrote this I confused myself to no end. The code/data of an rmodule has a set memory size which is associated with the .payload section. The relocation entries may increase the overall footprint of the memory size if the rmodule has no bss but a lot of relocations. Therefore, just compare relocation entries size plus the file size of the .payload section with the memory size of the paylod section. The .empty section is added only when we have not met the final target size.
