2009-08-17sparc,leon: Added support for AMBAPP bus.Konrad Eisele
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.

2008-12-07sparc: Restore irq_trans_init() call in prom_create_node().David S. Miller
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 :-) Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-05sparc: Move prom_build_devicetree() into prom_common.cDavid S. Miller
To make this work we provide a dummy nop implementation of of_fill_in_cpu_data() for sparc32. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-05sparc: Match sparc32's build_tree() up to sparc64'sDavid S. Miller
Sparc64 uses a non-recursive sibling traversal algorithm that never got propagated into the sparc32 copy of this code. Sync them up. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-05sparc: Make sparc32's create_node() assign parent pointer.David S. Miller
This makes it match what sparc64's version does. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Commonize get_one_property() implementations.David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move property building code into prom_common.cDavid S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move 'unique_id' into prom_common.c and rename to 'prom_unique_id'David S. Miller
This will be used in a subsequent changeset. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-05sparc: Create common area for OF device layer code.David S. Miller
This is where common code implementations will go as we unify 32-bit and 64-bit OF device tree code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Create common header file for prom_{32,64}.cDavid S. Miller

2008-12-04sparc: prepare kernel/ for unificationSam Ravnborg
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 Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
