ff82fb46d4 When a partially initialised FDT-based device instance can't attach,
perhaps due to an interrupt configuration problem, do not try to free
device ivars that have not yet have been allocated.

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

8c4c7216e6 Properly implement bus_setup_intr so that it handles the configuration
of interrupts of direct children. Have the bus_config_intr and
bus_teardown_intr methods implemented by bus_generic_config_intr and
bus_generic_teardown_intr (resp) as we don't need to do anything
special outselves.

This removes all the ``#ifdef $arch'' code that was there because powerpc
didn't have a proper nexus and people tend to copy and paste stuff.

49a5225199 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.

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.

b67d11bbcc Change rman_manage_region() to actually honor the rm_start and rm_end
constraints on the rman and reject attempts to manage a region that is out
of range.
- Fix various places that set rm_end incorrectly (to ~0 or ~0u instead of
  ~0ul).
- To preserve existing behavior, change rman_init() to set rm_start and
  rm_end to allow managing the full range (0 to ~0ul) if they are not set by
  the caller when rman_init() is called.

ac3fe75f97 Call newbus_device_create() for PCI devices. Call pci_from_fdt_node()
for the newly created device_t, rather than the parent.

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)
