sh: Kill off the remaining ST40 cruft.

2007-11-07T02:13:55+00:00

The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.

In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

sh: Use boot_cpu_data for CPU probe.

2007-09-27T09:18:39+00:00

This moves off of smp_processor_id() and only sets the probe
information for the boot CPU directly. This will be copied out
for the secondaries, so there's no reason to do this each time.

This also allows for some header tidying.

sh: Disable L2 reporting for present URAM only parts.

2007-09-27T01:29:58+00:00

The probing logic works for both URAM and L2, with no way to
distinguish between the two. Disable the probing for now and
let the CPU subtypes that have this in a real L2 configuration
explicitly say so.

sh: Kill off volatile silliness in sq_flush_range().

2007-09-21T02:57:51+00:00

  CC      arch/sh/kernel/cpu/sh4/sq.o
arch/sh/kernel/cpu/sh4/sq.c: In function 'sq_flush_range':
arch/sh/kernel/cpu/sh4/sq.c:65: warning: passing argument 1 of 'prefetch' discards qualifiers from pointer target type

This didn't actually need to be volatile in the first place, so just
kill off the qualifier entirely.

sh: intc - mark data structures as __initdata

2007-09-21T02:57:50+00:00

With the intc core improved it is now possible to put the intc data
structures in the initdata section.

Version two of this patch puts the __initdata inside DECLARE_INTC_DESC()
and removes the __initdata included in the board specific r2d code.

sh: intc - add a clear register to struct intc_prio_reg

2007-09-21T02:57:49+00:00

We need a secondary register member in struct intc_prio_reg to support
dual priority registers used by ipi on x3.

sh: intc - remove redundant irq code for sh03, snapgear and titan

2007-09-21T02:57:47+00:00

This patch removes redundant board specific interrupt code for boards
using sh775x processors and 4 IRQ lines in "Individual Interrupt Mode"
aka IRLM.

Three boards are affected: sh03, snapgear and titan.

The right way to do this is to use cpu specific code provided by intc.
A nice side effect is that sh03 now compiles, board not BROKEN any more.

sh: intc - add support for SH7760

2007-09-21T02:57:46+00:00

This patch converts the cpu specific interrupt setup code for sh7760
from ipr + intc2 to intc. New vectors are also added to match the
information provided by the datasheet.

Vectors for IRQ4-IRQ7 are enabled by default. Use plat_irq_setup_pins()
if pins IRL0-3 should be used in IRLM mode.

The patch also adds the SIM block to the serial port platform data.
Version two of this patch fixes MMCIF problems reported by Manuel Lauss.

sh: missing symbol fix for sh4-202

2007-08-22T04:32:07+00:00

This patch adds a plat_irq_setup() symbol for sh4-202. Without
this fix it is impossible to build a working kernel using the
microdev_defconfig.
