• X60 now uses a single grub.cfg (for grub memdisk)
• X60 now uses a single grub.elf (payload)
• Added new native graphics code for X60 (replaces the old ‘replay’ code) from Vladimir Serbinenko: 5320/9 from review.coreboot.org

  • macbook21: Added ‘build-macbook21’ script and linked to it in ‘build’ (ROMs included under bin/macbook21/)
