This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.

This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: NJon Mason <jdmason@us.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.

This patch merges, to some extent, the PPC32 and PPC64 kexec implementations. We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions. The current PPC64 implementation becomes the "default" implementation for PPC64 which platforms can select if they need no special treatment. I've added these default callbacks to pseries/maple/cell/powermac, this means iSeries no longer supports kexec - but it never worked anyway. I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with PPC64. Judging by the comments it might be better named machine_kexec_non_of, or something, but at the moment it's the only implementation for PPC32 so it's the "default". Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we already have in setup-common.c on powerpc. All this does is call ppc_md.nvram_sync, which only powermac implements, so instead make machine_shutdown a ppc_md member and have it call core99_nvram_sync directly on powermac. I've also stuck relocate_kernel.S into misc_32.S for powerpc. Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on P5 LPAR and successfully kexec'ed. Should apply on top of 493f25ef. Signed-off-by: NMichael Ellerman <michael@ellerman.id.au> 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.

Since the files are now in arch/powerpc/platforms/powermac, the pmac_ prefix that they had is redundant. Signed-off-by: NPaul Mackerras <paulus@samba.org>

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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
