barebox:ubi attach time

[Barbier, Renaud]

Just to see if somebody has the following problem:

We have PPC or ARM platforms with a NOR containing barebox and a UBI volume with an ITB image.
The File system is on NAND.

If I boot the system, ubiattach and mount the NOR volume, then detach. On reboot it takes more time for barebox to ubiattach  the NOR boot volume. I have noticed that with on 2019.07 barebox branch and 2020.03. 

I ubidetach the volume from barebox then boot time is restored.

I will be off for 2 weeks I will not be able answer until 1st of September.
