Hi Patrick, Martin,
The coreboot.org mirror of the arm-trusted-firmware repo (https://review.coreboot.org/admin/repos/arm-trusted-firmware) seems to be half a year out of date. According to the description (although that may be out of date) it's still syncing from the old GitHub location (https://github.com/ARM-software/arm-trusted-firmware.git). The Trusted Firmware project switched a while ago to their own hosting solution and I probably forgot to let you know. The new upstream repository this should sync from is at: https://review.trustedfirmware.org/TF-A/trusted-firmware-a
Then again, it looks like the GitHub location is still kept up to date as a read-only mirror (https://github.com/ARM-software/arm-trusted-firmware/commits/master), so maybe this isn't the real source of the problem? Anyway, can you please take a look and figure out how to fix the syncing? (Or is this supposed to be done manually somehow?)
Thanks, Julius
