This conditionalizes gUSA support. gUSA is not supported on SMP configurations, and it's not necessary there anyways due to having other atomicity options (ie, movli.l/movco.l). Anything implementing the LL/SC semantics (all SH-4A CPUs) can switch to userspace atomicity implementations without requiring gUSA. This is left default-enabled on all UP so that glibc doesn't break. Those that know what they are doing can disable this explicitly. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The Maple bus is SEGA's proprietary serial bus for peripherals (keyboard, mouse, controller etc). The bus is capable of some (limited) hotplugging and operates at up to 2 M/bits. Drivers of one sort or another existed/exist for 2.4 and a rudimentary port, which didn't support the 2.6 device driver model was also in existence. This driver - for the bus logic itself and for the keyboard (other drivers will follow) are based on the code and concepts of those old drivers but have lots of completely rewritten parts. I have the maple bus code as a built in now as that seems the sane and rational way to handle something like that - you either want the bus or you don't.

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.

This patch converts the cpu specific 7750 setup code to use the new intc controller. Many new vectors are added and multiple processor variants including 7091, 7750, 7750s, 7750r, 7751 and 7751r should all have the correct vectors hooked up. IRLM interrupts can be enabled using ipr_irq_enable_irlm() which now is marked as __init. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This gets the SH cpufreq working again. We follow the changes in the AVR32 implementation for wrapping in to the clock framework. CPUs that wish to use this are required to define rate rounding primitives in order to satisfy clk_round_rate(). This works well enough for the common case, though we should look at unifying this driver across all of the platforms that implement clock framework support in one capacity or another.

This patch converts the cpu specific 7780 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type(). No external interrupts are registered by default. Use plat_irq_setup_pins() to select between IRQ or IRL mode. This patch also fixes the Alarm IRQ for the RTC.

This is the second version of the shared interrupt controller patch for the sh architecture, fixing up handling of intc_reg_fns[]. The three main advantages with this controller over the existing ones are: - Both priority (ipr) and bitmap (intc2) registers are supported - External pin sense configuration is supported, ie edge vs level triggered - CPU/Board specific code maps 1:1 with datasheet for easy verification This controller can easily coexist with the current IPR and INTC2 controllers, but the idea is that CPUs/Boards should be moved over to this controller over time so we have a single code base to maintain.

This kills off the BareCPU board as a "special" machvec, rather, we leave this as a default for when no other vector is available, or when we want to use it in combination with other vectors for testing with generic ops. As sh_mv is copied out anyways (or overloaded when an alternate vector is explicitly selected), this doesn't consume any additional memory. The generic machvec can be forcibly selected with sh_mv=generic, or by not having any other boards enabled. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This adds basic support for clockevents and clocksources, presently only implemented for TMU-based systems (which are the majority of SH-3 and SH-4 systems). The old NO_IDLE_HZ implementation is also dropped completely, the only users of this were on TMU-based systems anyways. More work needs to be done to generalize the TMU handling, in that the current implementation is rather tied to the notion of TMU0 and TMU1 utilization. Additionally, as more SH timers switch over to this scheme, we'll be able to gut most of the remaining system timer infrastructure that existed before.
