I have maybe misunderstood the thread and I have supposed you want to
send a V2 with the stuff related to secure moved to Kconfig, as
requested by Tom. For that reason, you find your patch tagged with
"Changes requested" in patchwork. Anyway, this can be done in a follow

I will completely agree if this is done separately.

Best regards,
Stefano
