Kyle Moffett e55d7f737d powerpc/mpic: Remove duplicate MPIC_WANTS_RESET flag
There are two separate flags controlling whether or not the MPIC is
reset during initialization, which is completely unnecessary, and only
one of them can be specified in the device tree.

Also, most platforms in-tree right now do actually want to reset the
MPIC during initialization anyways, which means lots of duplicate code
passing the MPIC_WANTS_RESET flag.

Fix all of the callers which currently do not pass the MPIC_WANTS_RESET
flag to pass the MPIC_NO_RESET flag, then remove the MPIC_WANTS_RESET
flag and make the code reset the MPIC by default.

Kyle Moffett be8bec56df powerpc/mpic: Invert the meaning of MPIC_PRIMARY
It turns out that there are only 2 in-tree platforms which use MPICs
which are not "primary":  IBM Cell and PowerMac.  To reduce the
complexity of the typical board setup code, invert the MPIC_PRIMARY bit
into MPIC_SECONDARY.

Kyle Moffett 996983b75c powerpc/mpic: Search for open-pic device-tree node if NULL
Almost all PowerPC platforms use a standard "open-pic" device node so
the mpic_alloc() function now accepts NULL for the device-node.  This
will cause it to perform a default search with of_find_matching_node().

Kyle Moffett 8bf4156896 powerpc: Consolidate mpic_alloc() OF address translation
Instead of using the open-coded "reg" property lookup and address
translation in mpic_alloc(), directly call of_address_to_resource().
This includes various workarounds for special cases which the naive
of_address_translate() does not.

Afterwards it is possible to remove the copiously copy-pasted calls to
of_address_translate() from the 85xx/86xx/powermac platforms.

Dmitry Eremin-Solenikov 46d026ac10 powerpc/85xx: consolidate of_platform_bus_probe calls
85xx board files have a lot of duplication in *_publish_devices()/
*_declare_of_platform_devices() functions. Merge that into a single
function common to most of the boards.

Paul Gortmaker ead53f22dc powerpc: remove non-required uses of include <linux/module.h>
None of the files touched here are modules, and they are not
exporting any symbols either -- so there is no need to be including
the module.h.  Builds of all the files remains successful.

Even kernel/module.c does not need to include it, since it includes
linux/moduleloader.h instead.

Anton Vorontsov 84ba4a5899 powerpc/85xx: Move gianfar mdio nodes under the ethernet nodes
Currently it doesn't matter where the mdio nodes are placed, but with
power management support (i.e. when sleep = <> properties will take
effect), mdio nodes placement will become important: mdio controller
is a part of the ethernet block, so the mdio nodes should be placed
correctly. Otherwise we may wrongly assume that MDIO controllers are
available during sleep.

Becky Bruce f465df81a8 powerpc: Move memory size print into common show_cpuinfo for 32-bit
Most of the platforms were printing the size of the memory
in their show_cpuinfo implementations. This moves that to
the common show_cpuinfo, so that all 32-bit platforms will
now print the size of memory.  I also update the code
to deal with the fact that total_memory is now a phys_addr_t.

Jeremy McNicoll bfd123bf91 [POWERPC] 85xx: SBC8548 - Add flash support and HW Rev reporting
The following adds local bus, flash and MTD partition nodes for
sbc8548. As well, a compatible field for the soc node, so that
of_platform_bus_probe() will pick it up.

Something that is provided through this newly added epld node
is the Hardware Revision which is now being utilized.
