This would explain why barebox_update -l doesn't list qspi, but you aren't getting
that far, apparently.

That shouldn't matter. barebox header should contain the necessary bits for muxing/clocks.
Device-Tree only becomes relevant later, when barebox itself needs to read/write the flash.
I'd postpone QSPI for now and check whether SD-Card boot works at all.

Ahmad
