sparc32: rename sparc_irq_config to sparc_config
This struct holds platform specific config and is thus not
limited to irq stuff.
Do not let the name confuse us to think this is irq only.

sparc: remove several unnecessary module.h include instances
Building an allyesconfig doesn't reveal a hidden need
for any of these. Since module.h brings in the whole kitchen
sink, it just needlessly adds 30k+ lines to the cpp burden.

sparc32: introduce build_device_irq
build_device_irq() is used to encapsulate the plaform
specific details when we build an irq.
For now the default is a simple 1:1 but sun4d differs.
This patch refactors functionality - but does not change
the existing functionality.

of: Merge of_platform_bus_type with platform_bus_type
of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code. Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.
This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead. A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.
After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.

sparc/of: Move of_device fields into struct pdev_archdata
This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure. The reason
for this change is to unify the struct of_device definition amongst
all the architectures. It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.
A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).
This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device. After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.
This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.

of: eliminate of_device->node and dev_archdata->{of,prom}_node
This patch eliminates the node pointer from struct of_device and the
of_node (or prom_node) pointer from struct dev_archdata since the node
pointer is now part of struct device proper when CONFIG_OF is set, and
all users of the old pointer locations have already been converted over
to use device->of_node.
Also remove dev_archdata_{get,set}_node() as it is no longer used by
anything.

The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated. This patch
makes all readers of these elements use device.of_node instead.
(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

driver-core: Add device node pointer to struct device
Currently, platforms using CONFIG_OF add a 'struct device_node *of_node'
to dev->archdata. However, with CONFIG_OF becoming generic for all
architectures, it makes sense for commonality to move it out of archdata
and into struct device proper.
This patch adds a struct device_node *of_node member to struct device
and updates all locations which currently write the device_node pointer
into archdata to also update dev->of_node. Subsequent patches will
modify callers to use the archdata location and ultimately remove
the archdata member entirely.

of: unify phandle name in struct device_node
In struct device_node, the phandle is named 'linux_phandle' for PowerPC
and MicroBlaze, and 'node' for SPARC. There is no good reason for the
difference, it is just an artifact of the code diverging over a couple
of years. This patch renames both to simply .phandle.
Note: the .node also existed in PowerPC/MicroBlaze, but the only user
seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't
look like the assignment between .linux_phandle and .node is
significantly different enough to warrant the separate code paths
unless ibm,phandle properties actually appear in Apple device trees.
I think it is safe to eliminate the old .node property and use
phandle everywhere.

sparc,leon: Added support for AMBAPP bus.
The device is a AMBA bus if it is a child of prom node "ambapp" (AMBA
plug and play). Two functions
leon_trans_init() and leon_node_init() (defined in
sparc/kernel/leon_kernel.c) are called in the
prom_build_tree() path if CONFIG_SPARC_LEON is
defined. leon_node_init() will build up the device
tree using AMBA plug and play. Also: a extra check was addes to
prom_common.c:build_one_prop()
in case a rom-node is undefined which can happen for SPARC-LEON
because it creates only a minimum
nodes to emulate sparc behaviour.

sparc: move of_device common code to of_device_common
This patch moves code common to of_device_32.c and of_device_64.c into
of_device_common.h and of_device_common.c.
The only functional difference is in sparc32 where of_bus_default_map is
used in place of of_bus_sbus_map because they are equivelent.
There is still room for further code consolidation with some minor
refactoring.
Boot tested on sparc32 and compile tested on sparc64.

sparc: Fix bus type probing for ESP and LE devices.
If there is a dummy "espdma" or "ledma" parent device above ESP scsi
or LE ethernet device nodes, we have to match the bus as SBUS.
Otherwise the address and size cell counts are wrong and we don't
calculate the final physical device resource values correctly at all.
Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling
of LANCE and ESP parent nodes in of_device.c") was meant to fix this
problem, but that only influences the inner loop of
build_device_resources(). We need this logic to also kick in at the
beginning of build_device_resources() as well, when we make the first
attempt to determine the device's immediate parent bus type for 'reg'
property element extraction.
Based almost entirely upon a patch by Friedrich Oslage.

- use obj-$(CONFIG_SPARC32) for sparc32 specific files
- use <name>_$(BITS) for files where sparc64 has a _64 variant
- sparc64 directly include a few files where sparc32 builds them,
refer to these files directly (no BITS)
- sneaked in -Werror as used by sparc64
