* sh: IPR/INTC2 IRQ setup consolidation.Magnus Damm2007-07-19
| | | | | | | | | | This patch unifies the cpu specific interrupt setup functions for interrupt controller blocks such as ipr, intc2 and intc. There is no point in having separate functions for each interrupt controller, so let's clean this up. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: rework ipr codeMagnus Damm2007-06-15
| | | | | | | | | | | | | | | | | This patch reworks the ipr code by grouping the offset array together with the ipr_data structure in a new data structure called ipr_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks. This strategy has much in common with the recently merged intc2 code. One logic change has been made - the original ipr code enabled the interrupts by default but with this patch they are all disabled by default.

* sh: Fixup misaligned data for sh2 lockdep.Paul Mundt2007-06-11
| | | | | | | lockdep/irqflags tracing on SH-2 ends up with a misaligned branch, fix it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Tidy up dependencies for SH-2 build.Paul Mundt2007-06-11
| | | | | | | | | | | | SH-2 can presently get in to some pretty bogus states, so we tidy up the dependencies a bit and get it all building again. This gets us a bit closer to a functional allyesconfig and allmodconfig, though there are still a few things to fix up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off dead SH7604 support.Paul Mundt2007-06-07
| | | | | | | | This was added during 2.5.x, but was never moved along. This can easily be resurrected if someone has one they wish to work with, but it's not worth keeping around in its current form. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix bogus regs pointer in do_IRQ().Paul Mundt2007-03-14
| | | | | | | | SH-3 and SH-4 were trampling the register, and SH-2 wasn't even setting it in the first place. This ended up with some rather broken behaviour in the sysrq show_regs(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* Storage class should be before const qualifierTobias Klauser2007-02-17
| | | | | | | | | | | The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature.

* sh: Fixup cpu_data references for the non-boot CPUs.Paul Mundt2007-02-12
| | | | | | | There are a lot of bogus cpu_data-> references that only end up working for the boot CPU, convert these to current_cpu_data to fixup SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Use a jump call table for debug trap handlers.Paul Mundt2007-02-12
| | | | | | | | | | | | | | | | | This rips out most of the needlessly complicated sh_bios and kgdb trap handling, and forces it all through a common fast dispatch path. As more debug traps are inserted, it's important to keep them in sync for all of the parts, not just SH-3/4. As the SH-2 parts are unable to do traps in the >= 0x40 range, we restrict the debug traps to the 0x30-0x3f range on all parts, and also bump the kgdb breakpoint trap down in to this range (from 0xff to 0x3c) so it's possible to use for nommu. Optionally, this table can be padded out to catch spurious traps for SH-3/4, but we don't do that yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Exception vector rework and SH-2/SH-2A support.Yoshinori Sato2006-12-05
| | | | | | | | | This splits out common bits from the existing exception handler for use between SH-2/SH-2A and SH-3/4, and adds support for the SH-2/2A exceptions. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
