(also, promote the FSF-endorsed distros while you do it) - </li> - <li> - Add guides for GM45 laptops in docs/security/ - </li> - <li> - Add guides for GM45 laptops in docs/hardware/ - </li> - <li> - Convert documentation to Sphinx/ReST - See <a href="http://projects.mtjm.eu/work_packages/5">http://projects.mtjm.eu/work_packages/5</a> - and <a href="http://projects.mtjm.eu/work_packages/12">http://projects.mtjm.eu/work_packages/12</a> - </li> - <li> - LUKS key in initramfs: Add Trisquel documentation for docs/gnulinux/encrypted_trisquel.html. - See <a href="http://projects.mtjm.eu/work_packages/39">http://projects.mtjm.eu/work_packages/39</a> - </li> - <li> - PLCC flashing guide is needed: - <a href="http://blogs.coreboot.org/files/2013/07/vultureprog_shuttle_sbs.jpg">image</a>, - <a href="http://blogs.coreboot.org/files/2013/08/vultureprog_probing.jpg">image</a>, - <a href="http://blogs.coreboot.org/files/2013/06/superboosted2.jpg">image</a> - - work with mrnuke on getting info about vultureprog PLCC flashing into libreboot. Libreboot needs - server boards. <a href="https://github.com/mrnuke/vultureprog">https://github.com/mrnuke/vultureprog</a>, - <a href="https://github.com/mrnuke/qiprog">https://github.com/mrnuke/qiprog</a>, - <a href="https://github.com/mrnuke/vultureprog-hardware">https://github.com/mrnuke/vultureprog-hardware</a>. - He also uses the sigrok logic analyzer (free/libre): - <a href="http://www.dx.com/p/logic-analyzer-w-dupont-lines-and-usb-cable-for-scm-black-148945">http://www.dx.com/p/logic-analyzer-w-dupont-lines-and-usb-cable-for-scm-black-148945</a> - </li> - </ul> - - <h3>Project (institutional) improvements</h3> - <ul> - <li> - Add proper guidelines for contributions, - like <i>Development Guidelines</i> on the coreboot wiki. For instance, require - <i>Sign-off-by</i> in all commits for libreboot. Consulting with the FSF about this - (licensing@fsf.org). - </li> - <li> - <b>Libreboot needs to be factory firmware, not the replacement. It needs to be *the* firmware. - Consult with the openlunchbox project (and maybe others) on getting hardware manufactured - with libreboot support (out of the box, from the factory).</b> - </li> - <li> - PROPOSAL (only a proposal, for now): - Look into the possibility of expanding libreboot to support non-coreboot systems. (u-boot, for instance). - Currently, libreboot presents itself as a deblobbed coreboot distribution. There are other systems out there - that use other firmware, such as u-boot, which libreboot could theoretically support. This would mean that - the build scripts know how to build things other than just coreboot/grub. - <ul> - <li>Allwinner A10 (ARM) SoCs</li> - <li>PMON?</li> - <li>barebox (u-boot derivative)</li> - <li>etc</li> - <li> - <a href="http://zedboard.org/product/zedboard">http://zedboard.org/product/zedboard</a> - might be a candidate, according to the main developer of openlunchbox. - </li> - </ul> - </li> - <li> - Set up a routine (project-wise) for testing each system with the latest kernel version. - See <a href="http://projects.mtjm.eu/work_packages/22">http://projects.mtjm.eu/work_packages/22</a> - and <a href="http://projects.mtjm.eu/work_packages/21">http://projects.mtjm.eu/work_packages/21</a> - </li> - </ul> - - <h3>EC firmware</h3> - <p> - <a href="http://www.coreboot.org/Embedded_controller">http://www.coreboot.org/Embedded_controller</a> - Replace this on all libreboot targets. Some laptops use an extra SPI flash chip for the EC, some - have EC in the main chip, some don't use SPI flash at all but have the firmware inside the EC chip itself. - If the EC has integrated flash then you need to be able to get to the pins on the chip or be able to program them over LPC or SPI (if they have that feature). - The lenovo laptops currently supported in libreboot all use H8 EC chips (contains flash inside the chip). - Read the datasheets on how to externally programme the EC.
