This patch adds a shared SH-Mobile ARM specific CPUIdle implementation supporting WFI only at this point. It serves as a common point for late registration of the arch-specific CPUIdle code, and supports adding extra sleep modes using the callback shmobile_cpuidle_setup() together with shmobile_cpuidle_modes[].

Add sh7372 Core Standby sleep mode support and tie it in with the shared SH-Mobile ARM suspend code. The Core Standby mode is the lightest sh7372-specific sleep mode, cutting power to the ARM core excluding the L2 cache. Any interrupt source can be used for wakeups. The low level portion of this code is based on the TI OMAP sleep code in sleep34xx.S, thanks to them. Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

* Set receive enable and transmit enable bits of SCASCR0 (E6C400089). Values previously written to this register was bogus. Curiously earlyprintk works with the previous code. * Remove duplicate initialisation of GPIO port 152, SCIFA0_TXD (0xE6053098). This should have no effect other than to very slightly reduce the amount of code.

This allows a ROM-able zImage to be written to MMC and for SuperH Mobile ARM to boot directly from the MMCIF hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it. Cc: Magnus Damm <magnus.damm@gmail.com> Russell, please consider merging this for 2.6.38. This patch depends on: * "mmc, sh: Move MMCIF_PROGRESS_* into sh_mmcif.h" which will be merged though Paul Mundt's rmobile sh-2.6. The absence of this patch will break the build if the (new) CONFIG_ZBOOT_ROM_MMCIF option is set. There are no subtle side-effects. v2: Addressed comments by Magnus Damm * Fix copyright in vrl4.c * Fix use of #define CONFIG_ZBOOT_ROM_MMCIF in mmcif-sh7372.c * Initialise LED GPIO lines in head-ap4evb.txt instead of mmcif-sh7372.c as this is considered board-specific. v3: Addressed comments made in person by Magnus Damm * Move mmcif_loader to be earlier in the image and reduce the number of blocks of boot program loaded by the MaskRom from 40 to 8 accordingly. * Move LED GPIO initialisation into mmcif_progress_init - This leaves the partner jet script unbloated Other * inline mmcif_update_progress so it is a static inline in a header file v4: * Use htole16() and htole32() in v4rl.c to ensure that the output is little endian v5: Addressed comments by Russell King * Simplify assembly code * Jump to code rather than an address <- bug fix * Use (void __iomem *) as appropriate Roll in mackerel support * This was previously a separate patch, only because of the order in which this code was developed Signed-off-by: NSimon Horman <horms@verge.net.au> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Add INTCS support for the sh73a0 processor. The interrupts on the sh73a0 processor are managed through controllers such as GIC, INTCS and INTCA. The ARM cores use the GIC as primary interrupt controller and the INTCS and INTCA are hanging off the GIC as cascaded interrupt controllers. Peripherals connected both to the GIC and the INTC controllers should if possible only use the GIC. If no GIC connection is available then INTCS and INTCA may be used instead.

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.

Add SMP support for ag5evm and the sh73a0 processor. Onlining and offlining works well, but at this point offlined processor cores are not put into sleep mode. There is no spinlock for syncing the secondary core with the first one in this implementation. The code instead relies on the cpu_online() check in __cpu_up().

Add SMP base support for R-Mobile / SH-Mobile processors. This patch contains all base code to support CONFIG_SMP regardless of ARCH_SHMOBILE processor type. Both local timer and CPU hotplug are supported, but no processor specific code is included. At this point only the default behavior is in place, so a single core will always be used even though CONFIG_SMP is enabled on multicore systems. The SMP Kconfig entry for arch/arm/Kconfig is excluded from this patch to simplify merging. Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.
