As of commit 9a1091ef ("irqchip: gic: Support hierarchy irq domain."), the APE6EVM legacy board support is known to be broken. The IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the legacy platform board code. To fix this issue specific to non-muliplatform r8a73a4 and APE6EVM: 1) Instantiate the GIC from platform board code and also 2) Skip over the DT arch timer as well as 3) Force delay setup based on DT CPU frequency With these 3 fixes in place interrupts on APE6EVM are now unbroken. Partially based on legacy GIC fix by Geert Uytterhoeven, thanks to him for the initial work.

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.

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.

Fix interrupt priority level handling on SH-Mobile ARM. SH-Mobile ARM platforms using multiple interrupt priority levels need this patch to fix a potential dead lock that may occur if multiple interrupts with different levels are pending simultaneously. The default INTC configuration is to use the same priority level for all interrupts, so this issue does not trigger by default. It is however common for board code to override the interrupt priority for certain interrupt sources depending on the application. Without this fix such boards may lock up. In detail, this patch updates the INTC code in entry-macro.S to make sure that the INTLVLA register gets set as expected. To trigger this bug modify the board specific code to adjust the interrupt priority level for the ethernet chip. After changing the priority level simply use flood ping to drown the board with interrupts. This patch applies to INTCA-based processors such as sh7372, sh7377 and sh7372. GIC-based processors are not affected. Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

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.
