* sh: Fix up DSP context save/restore.Michael Trimarchi2009-04-04
| | | | | | | | | | | | | | | | There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().

* sh: hibernation supportMagnus Damm2009-03-09
| | | | | | | | | | | | | | | | | Add Suspend-to-disk / swsusp / CONFIG_HIBERNATION support to the SuperH architecture. To suspend, use "swapon /dev/sda2; echo disk > /sys/power/state" To resume, pass "resume=/dev/sda2" on the kernel command line. The patch "pm: rework includes, remove arch ifdefs V2" is needed to allow the generic swsusp code to build properly. Hibernation is not enabled with this patch though, a patch setting ARCH_HIBERNATION_POSSIBLE will be submitted later.

| | | | | | | | | | | | This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead.

* sh: intc - remove default interrupt priority tablesMagnus Damm2008-01-27
| | | | | | | | | | | | | This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Preparation for uncached jumps through PMB.Stuart Menefy2008-01-27
| | | | | | | | | | | | Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.

* sh: GUSA atomic rollback support.Stuart Menefy2008-01-27
| | | | | | | | | | This implements kernel-level atomic rollback built on top of gUSA, as an alternative non-IRQ based atomicity method. This is generally a faster method for platforms that are lacking the LL/SC pairs that SH-4A and later use, and is only supportable on legacy cores.

* sh: Use boot_cpu_data for CPU probe.Paul Mundt2007-09-27
| | | | | | | | | | 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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - mark data structures as __initdataMagnus Damm2007-09-20
| | | | | | | | | | | 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.

* rtc: rtc-sh: Support 4-digit year on SH7705/SH7710/SH7712.Paul Mundt2007-09-20
| | | | | | | | | | | | | | All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.
