Paul Gortmaker cdd0b0ac12 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.

Sam Ravnborg 7671fa22af sparc32: always register a PROM based early console
Do not require user to add "-p" to boot arguments to see
early info printed to prom console.

This is similar to the sparc64 functionality - which was added with:
3c62a2d347 ("[SPARC64]: Always register
a PROM based early console.")

Daniel Hellstrom 9663eb21fc SPARC/LEON: avoid AMBAPP name duplicates in openprom fs when REG is missing
When the REG property is not available the NODE-ID is used as an unique
identifier in order to avoid filesystem name duplicates in /proc/openprom
filesystem

Konrad Eisele e63829de3d 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.

David S. Miller bf944c370a sparc: Restore irq_trans_init() call in prom_create_node().
This broke sparc64 in various ways.

Add an empty dummy hook in sparc32's prom_32.c so that we
can potentially handle things on that side similarly, and
in particular avoid a prom_common.c ifdef :-)

To make this work we provide a dummy nop implementation
of of_fill_in_cpu_data() for sparc32.

David S. Miller 4aef8c53fe sparc: Match sparc32's build_tree() up to sparc64's
Sparc64 uses a non-recursive sibling traversal algorithm
that never got propagated into the sparc32 copy of this
code.

Sync them up.

David S. Miller 59966e3b4e sparc: Commonize get_one_property() implementations.
Add final len assignment in sparc64's get_one_property() (it's necessary
to avoid unchecked return value warnings on the sparc32 side),
and mark name argument const on sparc32's copy.

David S. Miller b9e5567cda sparc: Move property building code into prom_common.c
Unfortunately there is some sparc32/sparc64 ifdef'ery in
here due to the difference in how the prom_firstprop()
and prom_nextprop() routines work.

This will be eliminated eventually.

Sam Ravnborg d670bd4f80 sparc: prepare kernel/ for unification
o sparc32 files with identical names to sparc64 renamed to <name>_32.S
o introduced a few Kconfig helpers to simplify Makefile logic
o refactored Makefile to prepare for unification
  - 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
o modified sparc/Makefile to use the new names for head/init_task
