That feature is enabled on most/all Tegra boards with PCI support. Hopefully nobody will miss it; I guess I haven't used it so I don't object to this change.
However, wouldn't it be better to remove CONFIG_CMD_PCI_ENUM from the config header rather than leaving the command enabled yet non-functional? Or are you planning on implementing this path in the near future?
I was looking for feedback on why anyone would use this option. It's not clear to me what it is for.
We can implement it for driver model if it is needed.
