I believe you are referring to Qualcomm's original LK bootloader. "lk1st" is actually the name of an alternative configuration in the lk2nd project that can be used to replace the first-stage bootloader on devices without secure boot, e.g. DB410c and a few smartphones. lk1st has exactly the same functionality as lk2nd and is therefore definitely not old and broken. Both support DTB selection, secondary CPU cores etc. :-) I don't think we put the cover letter into a merge commit message in the qcom tree, so there is no need to resend. I just wanted to clarify this. Thanks for cleaning this up! Stephan
