Hi Marek, Patrick,
the patches that made this change also include patch https://source.denx.de/u-boot/u-boot/-/commit/dcb9a80359d699cf659c95b9b6e660...
This patch was added so that when there are multiple identical SPI-NOR chips on the board, you can still select between them in the `mtd` command via the OF path. That's why the `mtd list` command lists OF path.
In the discussion with Tom, we also were talking about backwards compatibility with mtdparts, and if I remember correctly, the conclusion was that mtdparts is deprecated: - many configs with MTDPARTS can now be converted to define the partitions via OF - the remaining which can't need their mtd driver updated
Afterwards there will be no need for mtdpart.
I think this is the correct solution here. Not the one where we are returning back to the "norN" names.
Marek
