Two commits in particular to point out include:
Add support for XHCI (USB 3.0) - For AMD/Parmer platforms, there is now USB 3.0 support when using this open-source BIOS/UEFI replacement.
qemu: add q35 support - Coreboot now supports Intel Q35 chipset emulation. Q35 chipset emulation was one of the new features -- as a more modern emulated motherboard chipset -- added to QEMU 1.4.
Plus there's been many other commits for those interested in this promising free software project.
