8966173312 Bump per-device interrupt limit to more reasonable default.
Some hardware like DMA and GPIO controllers might require
more then 8 interrupts per device instance.

2029d071db Merge Perforce changeset 219933 and portions of 219962 (omits changes to
unmerged BERI DTS files) to head:

  Use the OFW compatible string "mips,mips4k" rather than
  "mips4k,cp0" for interrupt control using MIPS4k CP0.

  Suggested by:   thompsa

  Implement a MIPS FDT PIC decode routine to use when no PIC has been
  configured, which assumes a cascade back to the nexus bus (e.g.,
  the on-board CP0 interrupt management parts on the MIPS).  If the
  soc bus in a MIPS DTS file is declared as "mips4k,cp0"-compatible,
  then this will be enabled.  This is sufficient to allow IRQs to be
  configured on BERI.

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.

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

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.

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.

3a47c0e263 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.

d1d3233ebd 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.
