2019-06-24cbfstool: Add ifittoolPhilipp Deppenwiese
Add the IntelFirmwareInterfaceTable-tool to modify the FIT. As cbfstool is overloaded with arguments, introduce a new tool to only modify FIT, which brings it's own command line syntax. Provide clean interface to: * Clear FIT * Add entry to CBFS file * Add entry to REGION * Delete entries * Add support for types other than 1 * Add support to dump current table * Add support for top-swap * Sort entries by type Most code is reused from existing cbfstool and functionality of cbfstool is kept. It will be removed once the make system uses only ifittool. Based on "Intel Trusted Execution Technology (Intel TXT) LAB Handout" and https://github.com/slimbootloader/slimbootloader .

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>
2015-04-25cbfstool: Clean up in preparation for adding new filesSol Boucher
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.

2014-02-02Add section header parsing and use it in the mk-payload stepRonald G. Minnich
This completes the improvements to the ELF file parsing code. We can now parse section headers too, across all 4 combinations of word size and endianness. I had hoped to completely remove the use of htonl until I found it in cbfs_image.c. That's a battle for another day. There's now a handy macro to create magic numbers in host byte order. I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe we can use it for the others too, but this is sensitive code and I'd rather change one thing at a time. To maximize the ease of use for users, elf parsing is accomplished with just one function: int elf_headers(const struct buffer *pinput, Elf64_Ehdr *ehdr, Elf64_Phdr **pphdr, Elf64_Shdr **pshdr) which requires the ehdr and pphdr pointers to be non-NULL, but allows the pshdr to be NULL. If pshdr is NULL, the code will not try to read in section headers. To satisfy our powerful scripts, I had to remove the ^M from an unrelated microcode file.

2014-01-29cbfs: fix issues with word size and endianness.Ronald G. Minnich
Add XDR functions and use them to convert the ELF headers to native headers, using the Elf64 structs to ensure we accomodate all word sizes. Also, use these XDR functions for output. This may seem overly complex but it turned out to be much the easiest way to do this. Note that the basic elf parsing function in cbfs-mkstage.c now works over all ELF files, for all architectures, endian, and word size combinations. At the same time, the basic elf parsing in cbfs-mkstage.c is a loop that has no architecture-specific conditionals. Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is no harm done. This code has been tested on all chromebooks that use coreboot to date. I added most of the extra checks from ChromeOS and they triggered a lot of warnings, hence the other changes. I had to take -Wshadow back out due to the many errors it triggers in LZMA. BUG=None TEST=Build and boot for Peppy; works fine. Build and boot for nyan, works fine. Build for qemu targets and armv8 targets.

2013-12-09cbfstool: Properly handle EOF in update_fit stepAlexandru Gagniuc
During the update_fit step, 'file_length' is used to determine how many bytes are left in the CBFS file. It was decremented in a loop from an array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before. Since 'mcus' is memset(0) externally, 'file_length' was never decremented. The loop exited when it reached a dummy terminator, usually 48 bytes of 0 which are internationally added to microcode blobs in coreboot. However, if that terminator is removed, the loop doesn't stop and continues until it segfaults.
