This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c. Signed-off-by: NPaul Mackerras <paulus@samba.org>

The nvram code formally known as bpa_nvram.c is rather generic really, so it is quite likely to be useful to future boards not based on cell. This patch puts it into arch/powerpc/sysdev. Signed-off-by: NArnd Bergmann <arndb@de.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Cell uses the same code as pSeries for flashing the firmware through rtas, so the implementation should not be part of platforms/pseries. Put it into arch/powerpc/kernel instead. Signed-off-by: NArnd Bergmann <arndb@de.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Currently when we first select memory model (FLAT, DISCONTIG, SPARSE) then select whether the machine is NUMA. However NUMA systems may not be FLAT. This constraint it not honoured and we may configure a NUMA/FLAT system. Reorder the configuration such that we choose NUMA first which allows us to only list the memory models which are valid. We now default NUMA for known NUMA systems. Note that this new order also matches that used in x86.

SMP still needs more work but UP gets as far as starting userspace at least. This uses the 64-bit-style code for spinning up the cpus. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This is so that the 32-bit CHRP code can use it. The MPC106 initialization code is now in arch/powerpc/sysdev/grackle.c and is controlled by CONFIG_PPC_MPC106. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This splits arch/ppc64/kernel/rtas.c into arch/powerpc/kernel/rtas.c, which contains generic RTAS functions useful on any CHRP platform, and arch/powerpc/platforms/pseries/rtas-fw.[ch], which contain some pSeries-specific firmware flashing bits. The parts of rtas.c that are to do with pSeries-specific error logging are protected by a new CONFIG_RTAS_ERROR_LOGGING symbol. The inclusion of rtas.o is controlled by the CONFIG_PPC_RTAS symbol, and the relevant platforms select that. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This changes the parameters for i8259_init so that it takes two parameters: a physical address for generating an interrupt acknowledge cycle, and an interrupt number offset. i8259_init now sets the irq_desc[] for its interrupts; all the callers were doing this, and that code is gone now. This also defines a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and makes the platforms that need it select that symbol. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to arch/powerpc/platforms/powermac/*.c and makes various minor tweaks elsewhere. On the powermac we now initialize ppc_md by copying the whole pmac_md structure into it, which required some changes in the ordering of initializations of individual fields of it.

On ARCH=ppc64 we were getting htab_hash_mask recalculated to the correct value for our particular machine by accident. In the merge tree, that code was commented out, so htab_hash_mask was being corrupted. We now set ppc64_pft_size instead which gets htab_has_mask calculated correctly for us later. We should put an ibm,pft-size property in the device tree at some point. Also set -mno-minimal-toc in some makefiles. Allow iSeries to configure PROC_DEVICETREE.

These days there is no good reason to run a ppc32 kernel on a 64-bit cpu, rather than a ppc64 kernel, so remove the config option and a bunch of code (and ifdefs) from head.S. Signed-off-by: NPaul Mackerras <paulus@samba.org>

Use idle_power4.S from ppc64 as we are not going to support 32 bit power4 in the merged tree. Merge ppc64 traps.c into powerpc traps.c: use ppc64 versions of exception routine names (as they don't have StudlyCaps) make all the versions if die() have the same prototype Signed-off-by: NStephen Rothwell <sfr@canb.auug.org.au>

This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting.
