2015-09-22coreboot: introduce commonlibAaron Durbin
Instead of reaching into src/include and re-writing code allow for cleaner code sharing within coreboot and its utilities. The additional thing needed at this point is for the utilities to provide a printk() declaration within a <console/console.h> file. That way code which uses printk() can than be mapped properly to verbosity of utility parameters.

2015-09-16cbfstool: expose rmodule logicAaron Durbin
In order to allow cbfstool to add XIP romstage on x86 without doing the 'cbfstool locate', relink, then 'cbfstool add' dance expose the core logic and of rmodule including proving an optional filter. The filter will be used for ignoring relocations to the .car.global region. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built rambi.

The core logic of the rmodule parser is ideal for processing romstage ELF files for XIP. To that end start the work of exposing the logic from rmodule so cbfstool can take advantage of it.

2015-09-09rmodtool: make rmodule parameter section optionalAaron Durbin
There are currently 2 uses for rmodule programs: stand alone programs that are separate from the coreboot stages and a relocatable ramstage. For the ramstage usage there's no reason to require a rmodule parameter section. Therefore make this optional. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built ramstage w/ normal linking (w/o a rmodule parameter section). No error.

2015-09-09rmodule: use program.ld for linkingAaron Durbin
Bring rmodule linking into the common linking method. The __rmodule_entry symbol was removed while using a more common _start symbol. The rmodtool will honor the entry point found within the ELF header. Add ENV_RMODULE so that one can distinguish the environment when generating linker scripts for rmodules. Lastly, directly use program.ld for the rmodule.ld linker script. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built rambi and analyzed the relocatable ramstage, sipi_vector, and smm rmodules.

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.

2014-08-27rmodtool: 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.

2014-03-20util: add rmodtool for parsing ELF files to rmodulesAaron Durbin
The current implementation of creating rmodules relies on invoking the linker in a certain manner with the relocations overlaid on the BSS section. It's not really surprising that the linker doesn't always behave the way one wants depending on the linker used and the architecture. Instead, introduce rmodtool which takes an ELF file as an input, parses it, and creates a new ELF file in the format the rmodule loader expects.
