Prerequisites:
- the board with U-Boot and installed Linux OS on eMMC
- g_multi module in Linux OS that shares *one of the eMMC partitions*
(pay attention here) as a disk to Windows host
I also misunderstood your assumption above; You are developing a linux-based USB gadget for Windows (10)?
No.
Really? I've got messed up now. - Why do you need to use g_multi to access the disk? - Where is a disk attached to? - Are Linux and Windows running on the same board?

Now, when you format that exposed disk (which is actually a partition on eMMC!) in Windows, you will get nested partitioning.
So why do you want to access *that* partition from U-Boot on the board? I don't think it is a common case.
What I'm trying to do is to copy some bootables to that partition from Windows machine in order to boot them via U-Boot. That's allow me not to disturb stock image on that board.
If U-Boot is not going to support nested partitioning, perhaps I can submit a documentation fix to advertise this explicitly.
