Changes for this release (latest changes first, earliest changes last)

  • grub.cfg: Added (ahci1) to list of devices for ISOLINUX parser (CD/DVD) (this is needed for the X200 docking station).
  • grub.cfg: ISOLINUX parsing is now done on all USB partitions.
  • grub.cfg: Automatically switched to /boot/grub/libreboot_grub.cfg on a partition, if it exists.
  • libreboot_bin: added static ARM binaries for flashprog, cbfstool, ich9gen and ich9deblob (tested on beaglebone black).
  • Flashrom: removed redundant Macronix flashchip definitions (for X200 owners).
  • Flashrom: added whitelist for ThinkPad X200.
  • X200: fixed uneven backlight (at low levels)
  • ich9macchange (new script, uses ich9gen): for changing the default MAC address on X200 ROM images.
  • ich9gen: added capability to change the default MAC address (and update the checksum)
  • ich9deblob: added new utility ich9gen: this can generate a descriptor+gbe image without a factory.rom dump present.
  • Modified ich9deblob to use a struct for Gbe, documenting everything.
  • Massively updated the ich9deblob utility: re-factored everything completely.
  • Enabled cstates 1 and 2 on macbook21. This reduces idle heat / power consumption.
  • buildrom-withgrub: disabled creation of *txtmode*.rom for X200 (only framebuffer graphics work)
  • Updated SeaBIOS (again)
  • docs/install/#flashprog_x200: improve instructions
  • Updated flashprog (again) - patches updated
  • Updated GRUB (again)
  • Updated coreboot (again)

  • build-release: include cbmem (statically compiled) in libreboot_bin
  • Documentation (X200): added software-based flashing instructions
  • Documentation: remove all references to the bus pirate (replaced with BBB flashing tutorials)
  • New board: ThinkPad X200S and X200 Tablet support added to libreboot
  • build: automatically find board names (configs) to build for
  • New board: ThinkPad X200 support added to libreboot
  • coreboot-libre config (all boards): enable USB dongle log output (for BeagleBone Black)
  • cleandeps: actually clean grubinvaders
  • .gitignore: add powertop directory
  • cleandeps: clean i945-pwm utility

  • Documentation: general cleanup.
  • builddeps-flashprog: reduce build commands to a single for loop
  • scripts (all): replace unnecessary rm -Rf with rm -f
  • docs/release.html: add lenovo g505s to the list of candidates
  • .gitignore: add libreboot_bin.tar.xz and libreboot_src.tar.xz
  • libreboot_bin.tar.xz: Include utils as statically linked binaries
    • This means that the user does not have to install build dependency or build from source anymore.
  • grub.cfg: Add more path checks to isolinux parser (more ISOs should work now)
  • Update SeaBIOS
  • x60flashfrom5 (new), for X60 users upgrading from 5th/early release
  • Update flashprog
  • Update GRUB
  • Updated coreboot-libre
    • i945: permanently set tft_brightness to 0xff (fixes bug on X60 where turning up brightness at max would make it loop back to low brightness)
  • getcb: Revert X60/T60 to legacy backlight controls
    • The ACPI brightness patches were abandoned and obsolete.
  • grub.cfg: Only load initrd.img if it exists. Add rw to linux line (for ProteanOS)

  • New links added to docs/security/x60_security and docs/security/t60_security
  • lenovobios_secondflash: Warn if BUCTS is not present. (not a dealbreaker. Can just pull out nvram battery/coin).
  • lenovobios_firstflash: Fail if BUCTS fails. (anti-bricking precaution)
  • Removed obnoxious warnings from flashing scripts, improved documentation instead.
  • scripts (all): add proper error checking (fail fast, fail early. Do not continue if there are errors)
  • buildrom-withgrub: rename image to boardname_layout_romtype.rom
  • buildrom-withgrub: don't move cbfstool, execute directly
  • resources/utilities/grub-assemble: add French Dvorak (BEPO) keyboard layout.
  • Documentation: add docs/hardware/x60_keyboard.html (show how to replace keyboard on X60/X60T)
  • Documentation: major cleanup (better structure, easier to find things)
  • docs/release.html: Remove Acer CB5 from list of future candidates.
    • Too many issues. Chromebooks are crippled (soldered RAM/storage/wifi) and have too many usability issues for the libreboot project.
  • docs/linux/grub_cbfs.html Major cleanup. Usability improvements.
  • flash (flashprog script): remove boardmismatch=force
    • This was put there before for users upgrading from libreboot r5 to r6, but also allows the user to flash the wrong image. For example, the user could flash a T60 image on an X60, thus bricking the system. It's almost certain that most people have upgraded by now, so remove this potentially dangerous option.
  • Documentation: update compatibility list for X60T LCD panels.
  • docs/release.html: add note about X60 Tablet board in X60/X60s
  • docs/howtos/grub_boot_installer.html: small corrections
  • docs/howtos/grub_boot_installer.html: improved readability, fixed html errors
  • Documentation (macbook21 related): clean up
