The bootloader spec defines a single /boot per device. This is very
good for the general purpose distribution usecase. This extension
is mostly useful for embedded systems (for which barebox was written).
On embdedded systems we often have images which contain both a kernel
and a rootfilesystem. These images are sometimes written to a device
multiple times for redundancy reasons. With this series no longer a
single /boot is required, but instead bootspec entries can be on
every partition of a device. So now we can not only 'boot emmc0', but
also 'boot emmc0.1' for booting a partition on am emmc device.
Also now a path containing bootspec entries can be given which will
be useful for NFS boot for example.
