Deleted pieces of code detect MBR-containig device as a FAT-type device,
if it's first partition contains a FAT filesystem. So, one can mount the first
partition of a hard drive containing FAT FS using the following command:
barebox: mount /dev/ata0.0 /mnt/0
as well as this one:
barebox: mount /dev/ata0 /mnt/1
Both commands mount the same FS.
This behaviour causes automount (mount -a) to mount FAT FS
on a first partition twice:
barebox: mount
none on / type ramfs
none on /dev type devfs
/dev/ata0 on /mnt/ata0 type fat
/dev/ata0.0 on /mnt/ata0.0 type fat
/dev/ata0.1 on /mnt/ata0.1 type ext4
