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

2007-10-04T16:02:54+00:00

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.

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

2007-10-04T01:02:09+00:00

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.

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

2007-10-03T12:20:17+00:00

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.

[POWERPC] Create and use CONFIG_WORD_SIZE

2007-10-02T23:12:02+00:00

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.

[POWERPC] clk.h interface for platforms

2007-10-02T23:11:56+00:00

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.

[POWERPC] iSeries: Clean up lparmap mess

2007-08-22T05:21:46+00:00

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.

[POWERPC] Rename 4xx paths to 40x

2007-08-20T12:27:07+00:00

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.

[POWERPC] Fix for assembler -g

2007-08-15T05:12:50+00:00

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

2007-07-29T23:45:38+00:00

Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid
confusion (among other things, with CONFIG_SUSPEND introduced in the

[POWERPC] Use global_number in ppc32 pci_controller

2007-06-29T06:58:37+00:00

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.
