Libreboot release 6 beta 5.
- build: added 'luks', 'lvm', 'cmosdump' and 'cmostest' to the list of
modules for grub.elf
- Documentation: added pics showing T60 unbricking (still need to
write a tutorial)
- build: include cmos.layout
(coreboot/src/mainboard/manufacturer/model/cmos.layout) files in
libreboot_bin
- Documentation: added ../docs/howtos/x60tablet_unbrick.html
- Documentation: added ../docs/howtos/t60_unbrick.html
- Documentation: added ../docs/howtos/t60_lcd_15.html
- Documentation: added ../docs/howtos/t60_security.html
- Documentation: added ../docs/howtos/t60_heatsink.html
- Documentation: Renamed RELEASE.html to release.html
- Documentation: removed pcmcia reference in x60_security.html (it's
cardbus)
- Documentation: added preliminary information about randomized seal
(for physical intrusion detection) in x60_security.html and
t60_security.html
- Documentation: added preliminary information about
preventing/mitigating cold-boot attack in x60_security.html and
t60_security.html
- Documentation: added info to ../docs/index.html#macbook21 warning
about issues with macbook21
- Documentation: X60/T60: added information about checking custom
ROM's using dd to see whether or not the top 64K region is
duplicated below top or not. Advise caution about this in the
tutorial that deals with flashing on top of Lenovo BIOS, citing the
correct dd commands necessary if it is confirmed that the ROM has
not been applied with dd yet. (in the case that the user compiled
their own ROM's from libreboot, without using the build scripts, or
if they forgot to use dd, etc).
- Split resources/libreboot/patch/gitdiff into separate patch files
(getcb script updated to accomodate this change).
- Re-added .git files to bucts
- Fixed the oversight where macbook21_firstflash wasn't included in
binary archives
