NVME o nLS1046A-RDB

[Renaud Barbier]

>From barebox:
-------------------

The node /dev/nvme0n1p1 does not exists only /dev/nvme0n1.
>From barebox, I saw that below once. 
It is not repeating at present whatever the command I use:
ERROR: ext4 ext40: probe failed: Invalid argument



> 
> does "md -s /dev/nvme0n1" work as expected?
