Remove svn:mergeinfo from the releng/10.0 branch.

After branch creation from stable/10, the stable/10 branch mergeinfo
was moved to the root of the branch.

Since there have not been any merges from stable/10 to releng/10.0
yet, we do not need to track any of the existing mergeinfo here.

Merges to releng/10.0 should now be done to the root of the branch.

For future branches during the release cycle, unless otherwise noted,
this change will be done as part of the stable/ and releng/ branch
creation.

Implement a driver for Robert Norton's PIC as an FDT interrupt
controller. Devices whose interrupt-parent property points to a beripic

device will have their interrupt allocation, activation, and setup
operations routed through the IC rather than down the traditional bus
hierarchy.

This driver largely abstracts the underlying CPU away allowing the
PIC to be implemented on CPU's other than BERI. Due to insufficient
abstractions a small amount of MIPS specific code is currently required
in fdt_mips.c and to implement counters.

MFP4: 223121 (FDT infrastructure portion)

Implement support for interrupt-parent nodes in simplebus. The current
implementation requires that device declarations have an interrupt-parent
node and that it point to a device that has registered itself as a
interrupt controller in fdt_ic_list_head and implements the fdt_ic
interface.

Add basic support for FDT to i386 & amd64. This change includes:
1. Common headers for fdt.h and ofw_machdep.h under x86/include
with indirections under i386/include and amd64/include.
2. New modinfo for loader provided FDT blob.
3. Common x86_init_fdt() called from hammer_time() on amd64 and
init386() on i386.
4. Split-off FDT specific low-level console functions from FDT
bus methods for the uart(4) driver. The low-level console
logic has been moved to uart_cpu_fdt.c and is used for arm,
mips & powerpc only. The FDT bus methods are shared across
all architectures.
5. Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.

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.

When a partially initialised FDT-based device instance can't attach,

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

Properly implement bus_setup_intr so that it handles the configuration

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.

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.

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.

FDT support for MIPS.

Add architecture specific files needed to compile MIPS with
flattened device tree support.

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.

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.

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.
