First, thanks for your work. I planned to upstream these boards myself
after the FSL QSPI spi-mem driver was merged in 5.1, but didn't have
time to finalize and send the patches.
Meanwhile we came up with a new naming scheme for our boards, that
hasn't been implemented yet. But I would like to take this chance to
implement the new scheme.
Also there are some more flavors of the SoM (with i.MX6ULL instead of
i.MX6UL, with 512MiB instead of 256MiB flash/RAM), that I would like to
add and for which common parts of the SoM dtsi would need to be factored
out to a separate file.
I would prefer to at least apply the naming changes before merging. The
additional board flavors could be added before merging or I could send
them as follow-up patches. What do you think?
Thanks,
Frieder
