of: Also print disabled nodes ...

It's confusing to set the status of a node to disabled and afterwards
it's invisible. Similarly it's confusing to be able to enable invisible
nodes.

Also print disabled nodes.

fdt: Fix dt memreserve entry ...

The fdt reserve map needs address/size values, not address/end values
like accidently done for generating the reserve entry for the dt.

of: populate devices based on "simple-bus" property ...

We used to populate the devices from the devicetree based on the
presence of the 'reg' property. This is incorrect since this only
allows us to probe devices with resources.
Instead use the 'simple-bus' property to see if we have iterate
deeper. This also registers devices with their buses as parents.

of: Add of_match_node function ...

To match a of_device_id arrays against a device_node. Same functionality
as in the kernel.

of: Call of_add_memory from of_probe ...

memory is always in /mem, so call of_add_memory from of_probe once
instead of in the recursive tree iteration. This makes it possible
to limit the device population to nodes with the "simple-bus" property
set.

of: When checking for existing devices also check resource end ...

When registering devices from the devicetree we check if these
devices already exist. When doing this not only check the resource
start but also the resource end.
This helps with the probing of simple buses for which child nodes
often begin at the very same address as the parents.

of: separate out "generic" memory bank adding ...

This patch separates out the "generic" memory
segment registration function (of_add_memory_bank())
from of_add_memory().
The MIPS architecture has different view on memory
resources than the ARM and PPC architectures
so the "generic" of_add_memory_bank() is
unusable for the MIPS architecture.
We can add MIPS-specific of_add_memory_bank()
into arch/mips code.

of: fix how an initrd is passed to Linux ...

Linux expects linux,initrd-end to contain the first unused address. As
this doesn't match the end semantic used by barebox (i.e. end contains
the last used address) adding one is necessary.

Without this change Linux fails for me to correctly extract a gzipped
cpio archive provided as initrd.

of: partitions: pass struct cdev as argument ...

pass a struct cdev instead of the cdev name to of_parse_partitions.
This is available to the caller anyway and makes it easier to use
additional stuff from the cdev (like knowing whether it's a mtd
device).
