[POWERPC] 8xx: Move softemu8xx.c from arch/ppc

2007-10-04T16:02:54Z

Previously, Soft_emulate_8xx was called with no implementation, resulting in build failures whenever building 8xx without math emulation. The implementation is copied from arch/ppc to resolve this issue. However, this sort of minimal emulation is not a very good idea other than for compatibility with existing userspaces, as it's less efficient than soft-float and can mislead users into believing they have soft-float. Thus, it is made a configurable option, off by default. Signed-off-by: Scott Wood Signed-off-by: Kumar Gala

[PPC] Use cpu setup routines from cpu_setup_44x.S for ARCH=ppc

2007-10-04T01:02:09Z

Commit 8112753bb2c0045398c89d0647792b39805f6d40 made 44x in ARCH=powerpc builds use cpu setup routines in cpu_setup_44x.S, but didn't make a similar change for ARCH=ppc, and consequently the ARCH=ppc builds fail with undefined symbols (since both use the same cputable.c). This fixes it by including cpu_setup_44x.S in the ARCH=ppc builds, and by taking out the now-redundant FPU initialization in arch/ppc/kernel/head_44x.S. Signed-off-by: Paul Mackerras

[POWERPC] 4xx: Introduce cpu_setup functionality to 44x platform

2007-10-03T12:20:17Z

This adds cpu_setup functionality for ppc44x platform. Low level cpu-spefic initialization routines should be placed in cpu_setup_44x.S and a callback should be added to cputable. The cpu_setup is invoked by identify_cpu() function at early init. Signed-off-by: Valentine Barshak Signed-off-by: Josh Boyer

[POWERPC] Create and use CONFIG_WORD_SIZE

2007-10-02T23:12:02Z

Linus made this suggestion for the x86 merge and this starts the process for powerpc. We assume that CONFIG_PPC64 implies CONFIG_PPC_MERGE and CONFIG_PPC_STD_MMU_32 implies CONFIG_PPC_STD_MMU. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] clk.h interface for platforms

2007-10-02T23:11:56Z

This provides an implementation of the interface for arch/powerpc using a set of function pointers in clk_functions. Platforms that want to support this interface should fill clk_functions and select CONFIG_PPC_CLOCK in Kconfig. Signed-off-by: Domen Puncer Signed-off-by: Paul Mackerras

[POWERPC] iSeries: Clean up lparmap mess

2007-08-22T05:21:46Z

We need to have xLparMap in head_64.S so that it is at a fixed address (because the linker will not resolve (address & 0xffffffff) for us). But the assembler miscalculates the KERNEL_VSID() expressions. So put the confusing expressions into asm-offsets.c. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] Rename 4xx paths to 40x

2007-08-20T12:27:07Z

4xx is a bit of a misnomer for certain things, as they really apply to PowerPC 40x only. Rename some of the files to clean this up. Signed-off-by: Josh Boyer Acked-by: David Gibson

[POWERPC] Fix for assembler -g

2007-08-15T05:12:50Z

ppc64 does the unusual thing of using #include on a compiler-generated assembly file (lparmap.s) from an assembly source file (head_64.S). This runs afoul of my recent patch to pass -gdwarf2 to the assembler under CONFIG_DEBUG_INFO. This patch avoids the problem by disabling DWARF generation (-g0) when producing lparmap.s.

Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION

2007-07-29T23:45:38Z

Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid confusion (among other things, with CONFIG_SUSPEND introduced in the next patch). Signed-off-by: Rafael J. Wysocki Signed-off-by: Linus Torvalds

[POWERPC] Use global_number in ppc32 pci_controller

2007-06-29T06:58:37Z

Make the pci_controller struct use global_number for the PHB domain number instead of index to match what ppc64 does and reuse its pci_domain_nr code. Introduced a pci-common.c to handle shared code between ppc32 & ppc64. Signed-off-by: Kumar Gala
