* ARM: remove disable_fiq and arch_ret_to_user macrosRob Herring2012-02-211-22/+0
| | | | | | | | | | | | | | | Now that most platforms don't need disable_fiq and arch_ret_to_user macros, we can remove the empty macros or empty entry-macro.S files.

* ARM: Make global handler and CONFIG_MULTI_IRQ_HANDLER mutually exclusiveMarc Zyngier2011-11-151-9/+0
| | | | | | | | | | | | | | | | | | | | | Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code requires the arch_irq_handler_default macro to be defined as a fallback. It turns out nobody is using that particular feature as both PXA and shmobile have all their machine descriptors populated with the interrupt handler, leaving unused code (or empty macros) in their entry-macro.S file just to be able to compile entry-armv.S. Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default, which allows to remove one test from the hot path. Also cleanup both PXA and shmobile entry-macro.S.

* ARM: gic: consolidate PPI handlingMarc Zyngier2011-10-231-3/+0
| | | | | | | | | | | | | | | | | | | | | | | PPI handling is a bit of an odd beast. It uses its own low level handling code and is hardwired to the local timers (hence lacking a registration interface). Instead, switch the low handling to the normal SPI handling code. PPIs are handled by the handle_percpu_devid_irq flow. This also allows the removal of some duplicated code.

* ARM: mach-shmobile: Rely on run-time IRQ handlersMagnus Damm2011-01-071-5/+18
| | | | | | | | | Remove now unused IRQ demux code. All R-Mobile and SH-Mobile processors should register IRQ demux handlers during run-time. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* ARM: mach-shmobile: Split out entry-macros in to GIC and INTC variants.Paul Mundt2010-11-181-100/+4
| | | | | | | | | Presently the entry macros are all globbed together, this simply splits them out in to their insular variants. Future work such as the GIC generalization will replace some of these and tidy the abstraction up further. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* ARM: mach-shmobile: Initial AG5 and AG5EVM supportMagnus Damm2010-11-181-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds initial support for Renesas SH-Mobile AG5. At this point the AG5 CPU support is limited to the ARM core, SCIF serial and a CMT timer together with L2 cache and the GIC. The AG5EVM board also supports Ethernet. Future patches will add support for GPIO, INTCS, CPGA and platform data / driver updates for devices such as IIC, LCDC, FSI, KEYSC, CEU and SDHI among others. The code in entry-macro.S will be cleaned up when the ARM IRQ demux code improvements have been merged. Depends on the AG5EVM mach-type recently registered but not yet present in arch/arm/tools/mach-types. As the AG5EVM board comes with 512MiB memory it is recommended to turn on HIGHMEM. Many thanks to Yoshii-san for initial bring up. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* ARM: mach-shmobile: optimize get_irqnr_preamble/and_base macrosMagnus Damm2010-02-091-1/+1
| | | | | | | | | Optimize the SH-Mobile interrupt assembly macros to avoid reloading the INTFLGA register address in case of multiple pending interrupts. Kindly pointed out by Russell King. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* ARM: mach-shmobile: SH-Mobile G3 support.Magnus Damm2010-02-081-0/+39
This adds preliminary support for the SH-Mobile G-series. The SH-Mobile G-series is a series of ARM/SH multi-core CPUs that aside from the ARM MPU are primarily composed of existing SH IP blocks. This includes initial support for the SH7367 (SH-Mobile G3) CPU and the G3EVM reference board. Only timer, serial console, and NOR flash are supported at this point. Patches for the interrupt controller, pinmux support, clock framework and runtime pm will be submitted as feature patches on top of this.
