287c5fdf95 Eliminate FDT_IMMR_VA define. 
This removes platform dependencies from <machine>/fdt.h for the benfit of
portability.

1dddc6de1e Move MRVL FDT fixups and PIC decode routine to a platform specific area. 
This allows for better encapsulation (and eliminates generic fdt_arm.c, at
least for now).

6496d826cc 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.

51b403ec50 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)
