* sparc: Use sparc64 version of prom/printf.cRobert Reif2008-12-084-50/+2
| | | | | | | | | | Use sparc64 version of prom/printf.c. The only differences for sparc32 is that prom_printf is no longer exported for modules which should be OK. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc: Restore irq_trans_init() call in prom_create_node().David S. Miller2008-12-073-5/+6
| | | | | | | | | | 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: unify kernel/cpuSam Ravnborg2008-12-074-169/+95
| | | | | | | | | | o use cpu_32.c as base o move all sparc64 definitions to the common cpu.c o use ifdef for the parts that differs and use cpu_32 as base o spitfire.h required a CONFIG_SPARC64 guard to fix build on 32 bit Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

* sparc: Always set AUDIT_ARCH, not just on sparc64.David S. Miller2008-12-051-1/+1
| | | | | | | | | | | | | Without fancy makefile rules it's not straightforward to prevent both arch/sparc/kernel/audit.o and lib/audit.o from both being used on sparc32. Since arch/sparc/kernel/audit.c is identical to lib/audit.c except some CONFIG_COMPAT protected sections of code, just use it on sparc32 too as that's the simplest way to fix this.

* sparc: report "Unknown CPU/FPU" for unknown cpu/fpuSam Ravnborg2008-12-052-5/+8
| | | | | | | | | | If we cannot determine the CPU or FPU report "Unknown CPU" or "Unknown FPU" like sparc64 does. And report with KERN_ERR that we cannot determine the CPU. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | 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>

* sparc: Commonize get_one_property() implementations.David S. Miller2008-12-052-2/+2
| | | | | | | | 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>
* sparc: Move property building code into prom_common.cDavid S. Miller2008-12-054-126/+83
| | | | | | | | | | 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>

Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.

| | | | | | | | | | | Identical named files renamed to <name>_32.S Refactored Makefile to prepare for unification.

* sparc,sparc64: unify prom/Sam Ravnborg2008-12-0412-11/+5
| | | | | | | | | | | | | | | | | | | | - all files with identical names copied and renamed to *_64.c - the remaning files copied as is - added sparc64 specific files to sparc/prom/Makefile - teach sparc64 Makefile to look into sparc/prom/ - delete unused Makefile from sparc64/prom/ linking order was not kept for sparc64 with this change. It was not possible to keep linking order for both sparc and sparc64 and as sparc64 see more testing than sparc it was natural to break linking order on sparc64. Should it have any effect it would be detected sooner this way. printf_32.c and printf_64.c are obvious candidates to be merged but they are not 100% equal so that was left for later Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

* sparc,sparc64: unify MakefileSam Ravnborg2008-12-046-62/+76
| | | | | | | | | | | | | | | | | | | | | | | To unify Makefile for sparc and sparc64 a few other steps was needed: 1) separate defconfig files for sparc and sparc64 is required, so locate these in arch/sparc/configs 2) removoval of hack in toplevel Makefile to deal with that headers was in a separate directory compared to the rest The unification of the Makefile required usage of several foo-$(CONFIG_SPARCnn) += due to a few directories pending unification. This will be cleaned up when we unify the remaining directories. Included in this patch are the deletion of a few files in sparc64 as they are no longer needed: Makefile + Kconfig. arch/sparc64/ will after this patch is applied only have four directories (prom, lib, kernel, boot) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
