sh: sh7724 ddr self-refresh changes

2009-08-15T03:58:50+00:00

This patch updates the SuperH Mobile sleep assembly code with
support for DBSC memory controller found in the sh7724 processor.

Without this fix the memory hooked up to the sh7724 processor
will never enter self-refresh mode before suspending to ram. The
effect of this is that the memory contents most likeley will be
lost upon resume which may or may not be what you want.

sh: convert processor device setup functions to arch_initcall()

2009-08-13T02:36:33+00:00

Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().

This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().

A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

sh: SH7786 SMP support.

2009-06-23T08:30:17+00:00

SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2
CPUs. This just wraps in to the existing SH-X3 SMP code with some minor
changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.

sh: Provide cpu_idle_wait() to fix up cpuidle/SMP build.

2009-06-23T08:30:17+00:00

Crib the x86 cpu_idle_wait() implementation and shove it in with the
idle code, subsequently enabling ARCH_HAS_CPU_IDLE_WAIT.

They never set PT_DTRACE, but clear it after do_execve().

sh: Fix declaration of __kernel_sigreturn and __kernel_rt_sigreturn

2009-06-18T09:25:21+00:00

GCC 4.5.0 complains about the declaration of variables
__kernel_sigreturn and __kernel_rt_sigreturn because they have type
void.  Correctly declare these symbols as functions to fix the
following error,

arch/sh/kernel/signal_32.c: In function 'setup_frame':
arch/sh/kernel/signal_32.c:368:14: error: taking address of expression of type 'void'
arch/sh/kernel/signal_32.c: In function 'setup_rt_frame':

sh: remove stray markers.

2009-06-18T04:38:26+00:00

arch/sh has a couple of stray markers without any users introduced
in commit 3d58695edbfac785161bf282dc11fd42a483d6c9.  Remove them in
preparation of removing the markers in favour of the TRACE_EVENT
macro (and also because we don't keep dead code around).
