There are several use cases where a redundant Linux system is needed. The
barebox bootchooser framework provides the building blocks to model different
use cases without the need to start from the scratch over and over again.
The bootchooser works on abstract boot targets, each with a set of properties
and implements an algorithm which selects the highest priority target to boot.
See the documentation contained in this patch for more information.

Non volatile device variables are used to make device parameters
persistent. They are like normal non volatile variables, but set
the values of the device parameters with the corresponding name.
Every nv variable beginning with nv.dev is a non volatile device
variable. They have the form nv.dev.<devname>.<paramname> and act
on the parameter <paramname> of the device named <devname>.
The non volatile device variables are designated for example for
video modes, ethernet device ip addresses or mtd partitioning.

It becomes a common case that the Kernel is loaded from the filesystem
which later becomes the rootfs. This adds a possibility to let bootm
automatically append the root= option to the kernel command line. This
is done when global.bootm.appendroot is true.

Some SoCs allow to store multiple boot images on a device in order to
improve robustness. This adds a -r option to barebox_update to indicate
we do not want to make an update but instead repair/refresh an existing
image. Handlers which want to support this feature must set the
BBU_HANDLER_CAN_REFRESH flag during registration.

Using NFS in conjunction with boot spec and the feature to let Barebox
auto generate a kernel command line must keep the options the NFS filesystem
was mounted in Barebox. This patch extends the kernel command line parameter
on demand if something different than the defaults are used.
The command:
barebox:/ boot nfs://myhost//root
expands to the kernel command line:
nfsroot=myhost:/root,v3,tcp
while the command:
barebox:/ boot nfs://myhost:2049//root
expands now to the kernel command line:
nfsroot=myhost:/root,v3,tcp,mountport=2049,port=2049

This patch makes it possible to automatically add a suitable root= option
for booting Linux from the same filesystem on which the bootspec entry
has been found. This adds an additional 'linux-appendroot' option to
bootspec which if set to 'true' will cause barebox to automatically
add a root= option. This currently works for NFS, UBIFS and regular
block devices like ATA, SD/MMC using the root=PARTUUID= mechanism.

This adds (back) support for non volatile variables. Non volatile
variables are variables which are stored in the environment over
reboot. They are used in the same way as the global variables, but
with a 'nv' command and device. The variables are stored under
/env/nv/, one variable per file. Adding a nv variable automatically
adds a global variable with the same name. Changing a nv variable
also changes the same global variable, but not the other way round.
This allows for example to configure the username as:
nv user=sha; saveenv
