state: find backend node with its reproducible name ...

When fixing up the kernels state nodes we depended on the full node path
of the input device tree. This does not work when the kernel device tree
has different names. This has happened lately when the i.MX6 device
trees got their leading zeroes removed from the node names.

Use of_find_node_by_reproducible_name() to find the node corresponding
to the storage backend node in the kernel device tree.

state: remove unused arguments from state_new_from_node() ...

state_new_from_node() has arguments describing the backend path. These
are never used in barebox, the backend path is always derived from the
device nodes backend description. Remove these arguments.

i2c: i2c_master_send(): don't leave flags uninitialized ...

Leaving the flags field unitialized can lead to performing
read operation instead of write operation.

which parameter it tried to set.

FIT: Allow to open buffer as FIT image ...

This adds fit_open_buf() which can open a buffer as FIT image.

FIT: Implement opening images with no configuration ...

different images can be grouped together to build a FIT configuration.
So far we only supported opening images as parts of configurations.
This patch adds support for opening images that are not part of a
configuration. This mode is used when the configuration parameter of
fit_open_image is NULL.

The main difference is in the way the RSA signature is checked. When
being part of a configuration all involved nodes (including the hash
nodes of the images, but not the image itself) are covered by the
signature, thus during opening an image only the validity of the image
data hash has to be checked. When not being part of a configuration,
the image data itself is signed and must be checked.

FIT: factor out some helper functions ...

Create and use fit_alloc_digest() and fit_read_rsa_public_key()
which we can use a second time in the next step.

FIT: move handle->verify check to fit_verify_hash() ...

Preparation for the next step which will allow to open
images which are not part of a configuration.

This has one change inside: We used to iterate over all
subnodes of a image expecting all of them containing a hash,
so it could happen that we check multiple hashes if more exist
or that we falsely interpret some unrelated subnode as hash node.
With this patch we expect the hash in a subnode named "hash@1"
as required by the FIT image format description.

FIT: store device_nodes in fit_handle ...

We need the /images and /configurations nodes more than once,
so store them in the fit_handle rather than searching for them
each time again.

FIT: Let user specify the configuration to use ...

The images in FIT images can be opened in two different ways. They
can be either opened directly based on their names in the images/
node or as part of a configuration based on their names in the
corresponding /configuration/ node.

So far we only supported the latter. To prepare supporting the former
we return a cookie belonging to the configuration from
fit_open_configuration() which we use in fit_open_image() to refer
to the desired configuration.

While at it document fit_open_configuration().

FIT: Do not pre-open images ...

Only do what fit_open_configuration() suggests: open the configuration,
but not the images in it.

bootm: FIT: do not depend on FIT pre-opened images ...

When calling fit_open_configuration the FIT code already opens
the images "kernel", "ramdisk" and "dtb". This does not fit well
into the FIT code, so make the bootm code independent of these
pre-opened images so that we can drop the opening from the FIT
code in the next step.

of: mtd: partition: Use reproducible node names for fixup ...

The full names of device nodes are not as stable as we like them
to be. Lately the leading zeroes in the i.MX6 device trees were
removed which led to the result that we can no longer find the
partition nodes in the to be fixed tree. Use reproducible names
to overcome this.

of: Add function to find the same node in another tree ...

For our device tree fixups we have to find a node corresponding to
another node in another device tree. We used to use the full name
to match the nodes, but this falls apart when nodes get renamed
or for example a new bus hierarchy is introduced. To make this
more robust we create reproducible names from device nodes which
mostly depend on the address in MMIO space, the reg property and
as a last resort the name of the device node.

bootchooser: Drop SHELL_NONE conflict ...

Earlier versions of the bootchooser code executed scripts,
thus had to depend on shell support. We do not need this anymore, so
the dependency can be dropped.

boot: Make independent of command support ...

The boot code works with command support disabled if we skip
support for boot scripts. Bail out before parsing boot scripts
and allow to build with command support disabled.
