If drivers want to fixup their specific instance they need some context
to know which instance they have to fixup.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.

Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

This patch converts users of of_tree_for_each_node to recently added
for_eacg_compatible_node helper. Also of_tree_for_each_node is removed
from public OF API.

Barebox of_find_node_by_path requires a node to be passed as start node
to start searching. Linux OF API does not pass this node and no current
user of it in barebox is passing anything else than the root node.
Therefore, we rename current function to of_find_node_by_path_from and
introduce a Linux OF API compatible of_find_node_by_path that always
passes the current root_node. Also, all current users of that function
are updated to reflect the API change.

Now that we are completely independent of libfdt remove the unused
code.

This makes of_find_node_by_path usable with multiple trees.

In order to be able to handle multiple devicetrees, do not assume
the tree to be unflattened is the barebox internal one. Instead,
just return a pointer to it and assign the barebox internal root_node
external to the unflatten function.

depending on the power domain register we need to disable sata or mmc
and update the cpu informations

take from Calxeda U-Boot git

Register the original dtb to /dev/firmware-dtb and the fixed dtb to /dev/dtb

the dtb is at 0x1000

if no dtb present use C code device

keep in C the timer/gpio/uart

have a nice tree
