Thanks for looking into this!

I'm not entirely sure on whose side the issue is, but I didn't receive your
mails, either from the U-Boot mailing list or directly from the Cc field. I
however could find the patch on lore.kernel.org... and I also received yours
and Dragan's exchange on patch 4 (but not the patch itself). Any chance you
received something from my mail server? Does anyone in Cc of this mail
actually received the mail?
No automatic reply from your mail server and the logs look good on my side,
with a 250 result on all sent patches. Strange indeed...

I think this is the wrong pin to use.
The routing of GPIO1_A6 is similar on RK3399 Puma and Pine64 RockPro64, but
it differs massively for the Firefly Roc PC.
However, a similar routing is done for GPIO1_A5 on the Firefly, I believe
that one is more appropriate. What do you think?
I just double-checked the schematics (ROC_3399_PC), looking at signal OTP_OUT_H
which is definitely connected to GPIO1_A6 (P26).
Also it clearly resets the board when toggled and solves the MMC reset issue
I was having on this exact board, so I'm rather confident that it's the right
one to use :)
At least we're on the same page for using OTP_OUT_H, but it's routed to
GPIO1_A5 on the schematics I found:

Mmmmmm seems like I was looking at the wrong schematics?
https://en.t-firefly.com/doc/download/page/id/51.html does route
GPIO1_A6 to the OTP_OUT_H signal..

So, the Roc PC, Roc PC Plus and Roc PC Pro all seem to have a similar
routing for this pin, therefore:
