* sparc: Move of_set_property_mutex acquisition outside of devtree_lock grab.David S. Miller2009-11-081-2/+2
| | | | | | | | Otherwise we try to sleep with preemption disabled, etc. Noticed by Thomas Gleixner. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc,leon: Added support for AMBAPP bus.Konrad Eisele2009-08-171-2/+8
| | | | | | | | | | | | | | | | | | 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: Call OF and MD cpu scanning explicitly from paging_init()David S. Miller2009-06-161-2/+0
| | | | | | | We need to split up the cpu present mask setup from the cpu_data initialization, and this is a first step towards that. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Clean arch-specific code in prom_common.cJulian Calaby2009-01-051-11/+3
| | | | | | | | | | | | | | | prom_nextprop() and prom_firstprop() have slightly different calling conventions in 32 and 64 bit SPARC. prom_common.c uses a ifdef guard to ensure that these functions are called correctly. Adjust code to eliminate this ifdef by using a calling convention that is compatible with both 32 and 64 bit SPARC.

* sparc: Restore irq_trans_init() call in prom_create_node().David S. Miller2008-12-071-2/+2
| | | | | | | | | | 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>

* sparc: Move prom_build_devicetree() into prom_common.cDavid S. Miller2008-12-051-5/+27
| | | | | | | 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>

* sparc: Move property building code into prom_common.cDavid S. Miller2008-12-051-0/+81
| | | | | | | | | | 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>
* sparc: Move 'unique_id' into prom_common.c and rename to 'prom_unique_id'David S. Miller2008-12-051-0/+1

* sparc: Create common area for OF device layer code.David S. Miller2008-12-051-0/+121
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>
