- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

If virtual addresses are not set use one to one mapping.
Do not map memory and IO space at address 0.

Preset (clear) the ranges we're supposed to fill from the FDT. If a
particular range (either I/O memory or I/O port) is not defined in
the FDT, we're not handing uninitialized structures back to our caller.

DEBUG is a kernel option. Don't define it here, as it breaks LINT.
Since DEBUG was subsequently undefined, this is just debugging left-
over.

Don't operate on the parent of the PCI node. It's the PCI node itself
that represents the host controller. This makes the FDT PCI support
working an a bare-bones manner. This needs a lot more work, of which
the beginning are at the end of the file, compiled-out with #if 0.

The intend being that both the Marvell PCIE and Freescale PCI/PCIX/PCIE
duplicate the same platform-independent domain initialization, that
should be moved into an unified implementation in the FDT code. Handling
of resources requires help from the platform. A unified implementation
allows us to properly support PCI devices listed in the device tree and
configured according to the device tree specification.

Convert Freescale PowerPC platforms to FDT convention.

The following systems are affected:

- MPC8555CDS
- MPC8572DS

This overhaul covers the following major changes:

- All integrated peripherals drivers for Freescale MPC85XX SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).

- This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
QUICC, UART, CFI.

- Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
ocpbus(4) driver, which was based on hard-coded config data.

Note that world for these platforms has to be built WITH_FDT.

Import the common Flattened Device Tree infrastructure.

o fdtbus(4) - the main abstract bus driver for all FDT-compliant systems. This
is a direct replacement for the many incompatible bus drivers grouping
integrated peripherals on embedded platforms (like obio(4), ocpbus(4) etc.)

o simplebus(4) - bus driver representing ePAPR style 'simple-bus' node, which
is an umbrella device for most of the integrated peripherals on a typical
system-on-chip device.

o Other components (common routines library, PCI node processing helper
functions)
