The implementation here should work fine with TPM 1.2, so the only reason to avoid the UEFI implementation is if it's buggy - but given current versions of Windows will use the TPM by default if it's available, I'd be surprised if there's any significant bugs in the wild. I'm not sure there's a real case where you'd have a TPM on a UEFI system without having working firmware support, and if you don't have the firmware support I don't know how you'd discover the TPM in the first place (eg, if it's on SPI we'd need a full SPI implementation in grub to talk to it) _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
