Nitpick: The term "the old, broken lk1st bootloader" is a bit misleading
here. 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
