2005-10-22Merge changes from linux-2.6 by handPaul Mackerras
2005-10-22ppc64: Use arch/powerpc/platforms/powermac for powermac build.Paul Mackerras
This switches the ARCH=ppc64 build to use arch/powerpc/platforms/powermac instead of arch/ppc64/kernel/pmac*, and deletes the latter set of files. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-22powerpc: Merge in 64-bit powermac support.Paul Mackerras
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. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20powerpc: Fix some bugs in the new merged time codePaul Mackerras
I had the sense of the test for when to use the old 601-style RTC registers inverted. pmac_calibrate_decr and via_calibrate_decr weren't setting ppc_tb_freq, on which all the further calculations depended. Lastly, update_gtod was losing the top 32 bits of the new tb_to_xs value. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20ppc64: Move init_boot_text call and conswitchp init into setup_archPaul Mackerras
This way they get done in one place for all platforms, and it is more consistent with what ppc32 does. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20ppc: rename pci_assign_all_busses to pci_assign_all_busesPaul Mackerras
... for consistency with ppc64 and to make merging easier. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20powerpc: Fix places where ppc_md.show_[per]cpuinfo was treated as intPaul Mackerras
I missed a few places where ppc code was still assuming that the ppc_md.show_[per]cpuinfo functions returned int. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20ppc64: Change ppc_md.get_cpuinfo to ppc_md.show_cpuinfoPaul Mackerras
... for consistency with ppc32; also add in ppc32's show_percpuinfo function. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20powerpc: Merge time.c and asm/time.h.Paul Mackerras
We now use the merged time.c for both 32-bit and 64-bit compilation with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32. This removes setup_default_decr (folds its function into time_init) and moves wakeup_decrementer into time.c. This also makes an asm-powerpc/rtc.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19powerpc: Merge machdep.hPaul Mackerras
A few things change for consistency between ppc32 and ppc64: idle functions return void; *_get_boot_time functions return unsigned long (i.e. time_t) rather than filling in a struct rtc_time (since that's useful to the callers and easier for pmac to generate); *_get_rtc_time and *_set_rtc_time functions take a struct rtc_time; irq_canonicalize is gone; nvram_sync returns void. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19ppc: Minor smp changes for consistency with ppc64Paul Mackerras
This makes platform code use the smp_ops variable directly instead of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments from the *_message_pass() functions, and removes the call to the never-implemented smp_ops->space_timers() function. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-17ppc32: use L1_CACHE_SHIFT/L1_CACHE_BYTESStephen Rothwell
instead of L1_CACHE_LINE_SIZE and LG_L1_CACHE_LINE_SIZE Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-14powerpc: move iSeries/HvCallPci.h to platforms/iseries/call_pci.hStephen Rothwell
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-14powerpc: move iSeries/HvCallHpt.h to platforms/iseries/call_hpt.hStephen Rothwell
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-14powerpc: eliminate DsaAddr from pci_dnStephen Rothwell
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-14powerpc: remove ISERIES_[SUB]BUS macrosStephen Rothwell
This allows us to simplify a couple of things. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-14powerpc: move iSeries/iSeries_pci.h to platforms/iseriesStephen Rothwell
The only real user of this file outside platforms/iseries was drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR() so we move that to abs_addr.h (and lowercase it). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-12powerpc: Bring in some changes made to arch/ppc and include/asm-ppc64Paul Mackerras
Recent commits upstream have changed files which are currently duplicated in arch/powerpc and include/asm-powerpc. This updates them with the corresponding changes. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-12Merge from Linus' treePaul Mackerras
2005-10-12powerpc: make iSeries boot againStephen Rothwell
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. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-12powerpc: pci_dn's should point to their device_node'sStephen Rothwell
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-11ppc: Various minor compile fixesPaul Mackerras
This fixes up a variety of minor problems in compiling with ARCH=ppc arising from using the merged versions of various header files. A lot of the changes are just adding #include <asm/machdep.h> to files that use ppc_md or smp_ops_t. This also arranges for us to use semaphore.c, vecemu.c, vector.S and fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-11powerpc: Remove xmon.h include from arch/powerpc/platforms/powermac/pic.cPaul Mackerras
... since it isn't needed. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-11powerpc: Remove 83xx from arch/powerpc/platforms/Makefile for nowPaul Mackerras
Since we don't have an 83xx directory or a 83xx/Makefile, having 83xx in causes make clean to fail. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Start merging 64-bit support into powermac filesPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Get iseries to compile with ARCH=powerpcPaul Mackerras
This moves the Device_List member from struct device_node to struct pci_dn, which cleans up the device_node and makes the code a little simpler. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: move lparmap.c to arch/powerpc/kernelPaul Mackerras
Since lparmap.s gets included in arch/powerpc/kernel/head_64.S, this avoids depending on a file in another directory. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: rename powermac files to remove pmac_ prefixPaul Mackerras
Since the files are now in arch/powerpc/platforms/powermac, the pmac_ prefix that they had is redundant. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: move pSeries files to arch/powerpc/platforms/pseriesPaul Mackerras
Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-06powerpc: Merge in the ppc64 version of the prom code.Paul Mackerras
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: Paul Mackerras <paulus@samba.org>
2005-10-02Merge rsync://ozlabs.org/sfr-git/for-paulus/Paul Mackerras
2005-10-01powerpc: make iSeries buildStephen Rothwell
Merge vmlinux.lds.S. Also remove arch/powerpc/kernel/vmlinux.lds which is a generated file. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-01powerpc: Get merged kernel to compile and run on 32-bit SMP powermac.Paul Mackerras
This updates the powermac SMP code to use the mpic driver instead of the openpic driver and fixes the SMP-dependent context switch code. We had a subtle bug where we were using interrupt numbers 256-259 for IPIs, but ppc32 had NR_IRQS = 256. Moved the IPIs down to use interrupt numbers 252-255 instead. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-30powerpc: Move lparmap.c to powerpc/platformsStephen Rothwell
Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-09-30ppc64 iseries: move some iSeries include filesStephen Rothwell
These files are only referenced from within arch/powerpc/platforms/iseries, so move them there. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-09-28Merge Stephen Rothwell's patchesPaul Mackerras
2005-09-28powerpc: Fixes to get the merged kernel to boot on powermac.Paul Mackerras
This merges ppc_ksyms.c, puts back the actual do_execve call in sys_execve, makes init_MMU call find_end_of_memory rather than ppc_md.find_end_of_memory (every platform has a device tree with a /memory node now, right?) and fixes some problems with the mpic initialization on newworld powermacs. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-28[PATCH] ppc32: make cur_cpu_spec a single pointer instead of an arrayKumar Gala
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 lets remove the dummy cpu_setup calls that just return. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-28ppc64 iSeries: use device_node instead of iSeries_Device_nodeStephen Rothwell

2005-09-28powerpc: Move iSeries_pci.c to powerpc/platform/iseriesStephen Rothwell
and rename it to pci.c. This also required moving arch/ppc64/kernel/pci.h into include/asm-powerpc (called ppc-pci.h. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-09-28powerpc: Move iSeries_iommu.c to powerpc/platforms/iseriesStephen Rothwell
