a86619e32d 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

1b1a4a52a8 Simplify simplebus_setup_intr and don't call MD code directly. We can
(and have to) trust our parent to handle interrupt configuration.

b2c2c39802 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.

01d5f155a1 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.

e1d4e01ec9 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)).

ca7ad903dc 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.

e5b89f2d70 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.

08955ceac0 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.

6e31b7a52f 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.

on a board, the interrupt pin alone is not unique.

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)
