UEFI over the opensource Coreboot?

• yuhong 12y ago
  I think it is similar to what ARM SBSA uses.

  These guys are ridiculously misguided. UEFI, and not coreboot which is used in all of the arm chromebooks. A server chip in a laptop at 12W. Yawn. Great idea but I'm not holding my breath.

    Coreboot can't boot any ARM64 chip. i7-2640M (one chip in the original x220) has a TDP of 35W.

  Tianocore EDK2, which they plan on using, is the reference UEFI implementation and is BSD-licensed. ARM actually develops and maintains the ARM-specific parts of the implementation.

    Some people (e.g. authors of [1]) consider the UEFI reference implementation to be of poor quality. There was an exploitable (for privilege escalation from typical userspace administrator to system management mode) integer overflow there, and it wasn't a particularly tricky one[1].
