b08c8c4870 libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>
Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include <libfdt.h>      -> #include <linux/libfdt.h>
  #include <libfdt_env.h>  -> #include <linux/libfdt_env.h>

018f530323 env: Rename common functions related to setenv()
We are now using an env_ prefix for environment functions. Rename these
commonly used functions, for consistency. Also add function comments in
common.h.

9f841559a5 qemu-ppce500: Update get_phys_ccsrbar_addr_early()
The logic of what fdt_get_base_address() will search for and return has
changed.  Rework get_phys_ccsrbar_addr_early() to perform the logic that
fdt_get_base_address used to perform.

18d3f46995 qemu-ppce500: pass 'range_id' around in pci_map_region
In pci_map_region(), pass 'range_id' to fdt_read_range(),
otherwise the same address will be mapped again in other
calls to pci_map_region()

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

b539534d12 PPC 85xx QEMU: Always assume 1 core
We only need u-boot to bother about a single core in the QEMU machine.
Everything that would require additional knowledge of more cores gets
handled by QEMU and passed straight into the payload we execute.

Because of this setup, it would be counterproductive to enable SMP support
in u-boot. We would have to rip CPUs out of already existing spin tables
and respin them from u-boot. It would be a pretty big mess.

So only assume we have a single core. This fixes errors about CONFIG_MP
being disabled.

fa08d39517 PPC 85xx: Add qemu-ppce500 machine
For KVM we have a special PV machine type called "ppce500". This machine
is inspired by the MPC8544DS board, but implements a lot less features
than that one.

It also provides more PCI slots and is supposed to be enumerated by
device tree only.

This patch adds support for the generic ppce500 machine and tries to
rely solely on device tree for device enumeration.
