1d1ffd9efb Add fdt_get_reserved_regions function. API is simmilar to fdt_get_mem_regions
It returns memory regions restricted from being used by kernel. These
regions are dfined in "memreserve" property of root node in the same
format as "reg" property of /memory node

8bb9363760 Merging of projects/armv6, part 4
r233822:
  Remove useless and wrong piece of code in fdt_get_range() which i
  overwrites passed phandle_t node. Modify debug printf in fdt_reg_to_rl()
  to be consistent (that is, print start and end *virtual* addresses).

r230560:
  Handle "ranges;"
  Make fdt_reg_to_rl() responsible for mapping the device memory, instead
  on just hoping that there's only one simplebus, and using fdt_immr_va as
  the base VA.

r230315
  Add a function to get the PA from range, instead of (ab)using
  fdt_immr_pa, and use it for the UART driver

aa15e881bb Respect phy-handle property in Ethernet nodes of the device tree.
This lets specify whereabouts of the parent PHY for a given MAC node
(and get rid of ugly kludges in mge(4) and tsec(4)).

07042bef45 Fix OF_finddevice error return value in case of FDT.
According to the open firmware standard, finddevice call has to return
a phandle with value of -1 in case of error.

This commit is to:
- Fix the FDT implementation of this interface (ofw_fdt_finddevice) to
  return (phandle_t)-1 in case of error, instead of 0 as it does now.
- Fix up the callers of OF_finddevice() to compare the return value with
  -1 instead of 0 to check for errors.
- Since phandle_t is unsigned, the return value of OF_finddevice should
  be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases
  as well.

2af3fc178e Introduce macro FDT_MAP_IRQ to map from an interrupt controller and
interrupt pin pair to a global IRQ number. When multiple PICs exist
on a board, the interrupt pin alone is not unique.

4f124b977c Eliminate FDT_IMMR_VA define.
This removes platform dependencies from <machine>/fdt.h for the benfit of
portability.

58158742f2 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)
