2006-12-04[POWERPC] Provide dummy hard_irq_enable/disable() for PPC32Michael Ellerman1-0/+3
To allow arch/powerpc/kernel/crash.c to build on 32-bit we need a definition of hard_irq_disable(). 32-bit doesn't support the lazy interrupt disabling mechanism, so on 32-bit hard_irq_disable() is simply local_irq_disable(). Add a definition for hard_irq_enable() just for completeness. This allows (KEXEC=y && PPC32=y) to build again. Broken since d04c56f73c30a5e593202ecfcf25ed43d42363a2.

2006-12-04[POWERPC] include/asm-powerpc/: "extern inline" -> "static inline"Adrian Bunk3-6/+6
"extern inline" generates a warning with -Wmissing-prototypes and I'm currently working on getting the kernel cleaned up for adding this to the CFLAGS since it will help us to avoid a nasty class of runtime errors. If there are places that really need a forced inline, __always_inline would be the correct solution. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-12-04[POWERPC] Add of_platform support for ROM devicesVitaly Wool3-0/+71
This adds support for flash device descriptions to the OF device tree. It's inspired by and partially borrowed from Sergei's patch "[RFC] Adding MTD to device tree.patch".

2006-12-04[POWERPC] pSeries/kexec: Fix for interrupt distributionMohan Kumar M1-19/+49
This allows any secondary CPU thread also to become boot cpu for POWER5. The patch is required to solve kdump boot issue when the kdump kernel is booted with parameter "maxcpus=1". XICS init code tries to match the current boot cpu id with "reg" property in each CPU node in the device tree. But CPU node is created only for primary thread CPU ids and "reg" property only reflects primary CPU ids. So when a kernel is booted on a secondary cpu thread above condition will never meet and the default distribution server is left as zero. This leads to route the interrupts to CPU 0, but which is not online at this time. We use ibm,ppc-interrupt-server#s to check for both primary and secondary CPU ids. Accordingly default distribution server value is initialized from "ibm,ppc-interrupt-gserver#s" property. We loop through ibm,ppc-interrupt-gserver#s property to find the global distribution server from the last entry that matches with boot cpuid.

2006-12-04[POWERPC] fix building without PCIArnd Bergmann1-0/+7
At least the ide driver calls pcibus_to_node, which is not defined when CONFIG_PCI is disabled. This adds a nop function for the !PCI case. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

2006-12-04[POWERPC] ps3: add a default zImage targetArnd Bergmann1-0/+1
It's currently not possible to build the default zImage target if PS3 is the only selected platform. This is a hack to fall back to building the pseries style zImage, so the build is successful. This will probably change in the future, if someone writes a PS3 specific boot wrapper. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2006-12-04[POWERPC] ps3: multiplatform build fixesArnd Bergmann8-11/+44
A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

2006-12-04[POWERPC] cell: fix building without spufsArnd Bergmann3-5/+5
It may be desireable to build a kernel for cell without spufs, e.g. as the initial kboot kernel. This requires that the SPU specific parts of the core dump and the xmon code depend on CONFIG_SPU_BASE instead of CONFIG_PPC_CELL. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

2006-12-04[POWERPC] spufs: always send sigtrap on breakpointArnd Bergmann1-6/+4
Currently, we only send a sigtrap if the current task is being ptraced. This is somewhat inconsistant, and it breaks utrace support in fedora. Removing the check should do the right thing in all cases. Cc: Ulrich Weigand <ulrich.weigand@de.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
