Libreboot release 6 beta 6.
- Added modified builddeb* scripts for Parabola GNU/Linux-libre: buildpac, buildpac-flashrom, buildpac-bucts (courtesy of Noah Vesely) - Documentation: updated all relevant areas to mention use of buildpac* scripts for Parabola users. - Documentation: added information showing how to enable or disable bluetooth on the X60 - MacBook1,1 tested! See ../docs/index.html#macbook11" - Documentation: fixed typo in ../docs/index.html#get_edid_panelname (get-edit changed to get-edid) - Documentation: added ../docs/howtos/x60_lcd_change/ (pics only for now) - Added gcry_serpent and gcry_whirlpool to the GRUB module list in the 'build' script (for luks users) - Libreboot is now based on a new coreboot version from August 23rd, 2014: Merged commits (relates to boards that were already supported in libreboot): - http://review.coreboot.org/#/c/6697/ - http://review.coreboot.org/#/c/6698/ (merged already) - http://review.coreboot.org/#/c/6699/ (merged already) - http://review.coreboot.org/#/c/6696/ (merged already) - http://review.coreboot.org/#/c/6695/ (merged already) - http://review.coreboot.org/#/c/5927/ (merged already) - http://review.coreboot.org/#/c/6717/ (merged already) - http://review.coreboot.org/#/c/6718/ (merged already) - http://review.coreboot.org/#/c/6723/ (merged already) (text-mode patch, might enable memtest. macbook21) - http://review.coreboot.org/#/c/6732/ (MERGED) (remove useless ps/2 keyboard delay from macbook21. already merged) - These were also merged in coreboot (relates to boards that libreboot already supported): - http://review.coreboot.org/#/c/5320/ (merged) - http://review.coreboot.org/#/c/5321/ (merged) - http://review.coreboot.org/#/c/5323/ (merged) - http://review.coreboot.org/#/c/6693/ (merged) - http://review.coreboot.org/#/c/6694/ (merged) - http://review.coreboot.org/#/c/5324/ (merged) - Documentation: removed the section about tft_brightness on X60 (new code makes it obsolete) - Removed all patches from resources/libreboot/patch/ and added new patch: 0000_t60_textmode.git.diff - Updated getcb script and DEBLOB script. - Updated configuration files under resources/libreboot/config/ to accomodate new coreboot version. - Removed grub_serial*.cfg and libreboot_serial*.rom, all configs/rom's are now unified (containing same configuration as serial rom's from before). - Documentation: updated ../docs/index.html#rom to reflect the above. - Updated GRUB to new version from August 14th, 2014. - Unified all grub configurations for all machines to a single grub.cfg under resources/grub/config/ - Updated flashrom to new version from August 20th, 2014 - Added getseabios and builddeps-seabios (builddeps and getall were also updated) - Added instructions to 'buildrom-withgrub' to include bios.bin.elf and vgaroms/vgabios.bin from SeaBIOS inside the ROM. - Added seabios (and sgavgabios) to grub as payload option in menu - Disabled serial output in Memtest86+ (no longer needed) to speed up tests. - MemTest86+ now works properly, it can output on the laptop screen (no serial port needed anymore). - Added getgrubinvaders, builddeps-grubinvaders scripts. Added these to getall and builddeps. - Added GRUB Invaders menu entry in resources/grub/config/grub.cfg - Added rules to builddeps-coreboot to build libpayload with TinyCurses. (added appropriate instructions to cleandeps script). - Commented out lines in resources/grub/config/grub.cfg for loading font/background (not useful anymore, now that GRUB is in text-mode). - Commented out lines in buildrom-withgrub that included backgrounds/fonts (not useful anymore, now that GRUB is in text-mode). - Added resources/utilities/i945-pwm/ (from git://git.mtjm.eu/i945-pwm), for debugging acpi brightness on i945 machines. - Added instructions for it in builddeps, builddeps-i945pwm, builddeb and cleandeps - 'build' script: removed the parts that generated sha512sum manifests (not needed, since release tarballs are GPG-signed) - 'build' script: removed the parts that generated libreboot_meta directory (not needed anymore, since _meta will be hosted in git) - Updated ../docs/index.html#build_meta (and other parts of documentation) to accomodate this change. - Documentation: simplified (refactored) the notes in ../docs/index.html#rom - 'build' script: removed the parts that generated libreboot_bin and added them to a new script: 'build-release' - Documentation: ../docs/index.html#build updated to reflect the above. - Removed 'sudo' from builddeb, builddeb-flashrom, powertop.trisquel6 and builddeb-bucts scripts (assuming that the user has it is a really bad idea). - Added all gcry_* modules to grub (luks/cryptomount): gcry_arcfour gcry_camellia gcry_crc gcry_dsa gcry_md4 gcry_rfc2268 gcry_rmd160 gcry_seed gcry_sha1 gcry_sha512 gcry_twofish gcry_blowfish gcry_cast5 gcry_des gcry_idea gcry_md5 gcry_rijndael gcry_rsa gcry_serpent gcry_sha256 gcry_tiger gcry_whirlpool - Added GNUtoo's list of GRUB modules (includes all of the gcry_* modules above), cryptomount should be working now. - Removed builddeb-bucts and builddeb-flashrom, merged them with builddeb (../docs/index.html updated accordingly) - Removed buildpac-bucts and buildpac-flashrom, merged them with buildpac (../docs/index.html updated accordingly) - Renamed builddeb to deps-trisquel (../docs/index.html updated accordingly) - Renamed buildpac to deps-parabola (../docs/index.html updated accordingly) - Documentation: removed all parts talking about build dependencies, replaced them with links to ../docs/index.html#build_dependencies - Documentation: emphasized more strongly on the documentation, the need to re-build bucts and/or flashrom before flashing a ROM image. - build-release: flashrom, nvramtool, cbfstool and bucts are no longer provided pre-compiled in binary archives, and are now in source form only. (to maximize distro compatibility). - Documentation: added ../docs/howtos/encrypted_trisquel.html showing how to setup a fully encrypted Trisquel installation (including /boot) and boot it from the GRUB payload. - 'build' script: replaced grub.elf assembly instructons, it's now handled by a utility added under resources/utilities/grub-assemble - Moved resources/grub/keymap to resources/utilities/grub-assemble/keymap, and updated that utility to use it - Documentation: removed useless links to pictures of keyboard layouts and unmodified layouts. - Removed all unused fonts from dejavu-fonts-ttf-2.34/ directory - 'buildrom-withgrub' script: updated it to create 2 sets of ROM's for each machine: one with text-mode, one with coreboot framebuffer. - Documentation: updated ../docs/index.html#rom to reflect the above - Deleted unused README and COPYING file from main directory - Removed some rm -rf .git* instructions from the get* scripts and moved them to build-release script - Split up default grub.cfg into 6 parts: extra/{common.cfg,txtmode.cfg,vesafb.cfg} and menuentries/{common.cfg,txtmode.cfg,vesafb.cfg} - buildrom-withgrub script uses these to generate the correct grub.cfg for each type of configuration. - grub_memdisk.cfg (used inside grub.elf) now only loads grub.cfg from cbfs. It no longer enables serial output or sets prefix. (menuentries/common.cfg does instead) - resources/grub/config/extra/common.cfg, added: - insmod instructions to load those modules: nativedisk, ehci, ohci, uhci, usb, usbserial_pl2303, usbserial_ftdi, usbserial_usbdebug - set prefix=(memdisk)/boot/grub - For native graphics (recommended by coreboot wiki): - gfxpayload=keep - terminal_output --append gfxterm - Play a beep on startup: - play 480 440 1 - Documentation: added note about 'fb=false' workaround for text-mode debian-installer (Trisquel net install) to ../docs/howtos/grub_boot_installer.html - Documentation: updated ../docs/howtos/grub_cbfs.html to make it safer (and easier) to follow.
