altivec_unavailable_exception is called without setting r3... it looks like the r3 that actually gets passed in as struct pt_regs *regs is the undisturbed value of r3 at the time the altivec instruction was encountered. The user actually gets to choose the pt_regs printed in the Oops! This fixes the oops by passing the correct pt_regs pointer to altivec_unavailable_exception.

The CONFIG_PPC_OF symbol is used to mean that the firmware device tree access functions are available. Since we always have a device tree with ARCH=powerpc, make CONFIG_PPC_OF always Y for ARCH=powerpc. This fixes some compile errors reported by Kumar Gala, but in a different way to his patch. This also makes prom_parse.o be compiled only if CONFIG_PPC_OF so that non-OF ARCH=ppc platforms will compile. Signed-off-by: NPaul Mackerras <paulus@samba.org>

ARCH=powerpc couldn't boot from BootX as it uses a "different" way of getting in the kernel. This patch adds the necessary trampolines, creating a flattened device-tree from the tree passed from MacOS, and initializing the btext engine early for really-early debugging.

This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

32-bit SMP powermacs weren't booting with ARCH=powerpc because the boot cpu wasn't saving away the state of various control registers, but the secondary CPUs were loading them from the uninitialized state. This adds the necessary save-state call. Signed-off-by: NPaul Mackerras <paulus@samba.org>

The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

This makes ppc use the syscalls.c from arch/powerpc/kernel, exports copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc), and consolidates the sys_fadvise64_64 implementations for 32-bit. Signed-off-by: NPaul Mackerras <paulus@samba.org>

We were initializing the btext stuff from prom_init(), thus breaking the rule that all communication between prom_init() and the rest of the kernel has to be via the flattened device tree. This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This brings in the ppc64 version of prom_init.c, prom.c and btext.c and makes them work for ppc32. This also brings in the new calling convention, where the first entry to the kernel (with r5 != 0) goes to the prom_init code, which then restarts from the beginning (with r5 == 0) after it has done its stuff. For now this also brings in the ppc32 version of setup.c. It also merges lmb.h. Signed-off-by: NPaul Mackerras <paulus@samba.org>

Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs. Additionally, made call_setup_cpu check to see if the cpu_setup pointer is NULL or not before calling the function.

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.

This allows cpus to be off-lined on 32-bit SMP powermacs. When a cpu is off-lined, it is put into sleep mode with interrupts disabled. It can be on-lined again by asserting its soft-reset pin, which is connected to a GPIO pin. With this I can off-line the second cpu in my dual G4 powermac, which means that I can then suspend the machine (the suspend/resume code refuses to suspend if more than one cpu is online, and making it cope with multiple cpus is surprisingly messy).

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!
