2011-12-13ARM: Kirkwood: Add configuration for MPP12 as GPIOArnaud Patard
The MPP12 is listed in the 6281 HW manual as output only but the iconnect board from iomega is using it as GPIO (there's a button connected on it). So, I'm adding a definition for the MPP12 as GPIO. As I've no informations about this and which kirkwood are "affected", I'm adding a new #define instead of modifying the current one for MPP12.

2011-12-13ARM: OMAP: am33xx: Update common omap platform filesAfzal Mohammed
This patch updates the common platform files with AM335X device support (AM33XX family). The approach taken in this patch is, AM33XX device will be considered as OMAP3 variant, and a separate SoC class created for AM33XX family of devices with a subclass type for AM335X device, which is newly added device in the family. This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x() checks will return success on AM335X device. A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3 to include support for AM33XX build. Also, cpu_mask and RATE_IN_XXX flags have crossed 8 bit hence struct clksel_rate.flags, struct prcm_config.flags and cpu_mask are changed to u16 from u8.

2011-12-13ARM: 7208/1: Add condition code checking to SWP emulation handler.Leif Lindholm
This patch fixes two separate issues with the SWP emulation handler: 1: Certain processors implementing ARMv7-A can (legally) take an undef exception even when the condition code would have meant that the instruction should not have been executed. 2: Opcodes with all flags set (condition code = 0xf) have been reused in recent, and not-so-recent, versions of the ARM architecture to implement unconditional extensions to the instruction set. The existing code would still have processed any undefs triggered by executing an opcode with such a value. This patch uses the new generic ARM instruction set condition code checks to implement proper handling of these situations.

2011-12-12ARM: kexec: use soft_restart for branching to the reboot bufferWill Deacon

2011-12-12ARM: stop: execute platform callback from cpu_stop codeWill Deacon
Sending IPI_CPU_STOP to a CPU causes it to execute a busy cpu_relax loop forever. This makes it impossible to kexec successfully on an SMP system since the secondary CPUs do not reset. This patch adds a callback to platform_cpu_kill, defined when CONFIG_HOTPLUG_CPU=y, from the ipi_cpu_stop handling code. This function currently just returns 1 on all platforms that define it but allows them to do something more sophisticated in the future. Signed-off-by: Will Deacon <will.deacon@arm.com>
2011-12-12ARM: reset: implement soft_restart for jumping to a physical addressWill Deacon
Tools such as kexec and CPU hotplug require a way to reset the processor and branch to some code in physical space. This requires various bits of jiggery pokery with the caches and MMU which, when it goes wrong, tends to lock up the system. This patch fleshes out the soft_restart implementation so that it branches to the reset code using the identity mapping. This requires us to change to a temporary stack, held within the kernel image as a static array, to avoid conflicting with the new view of memory. Signed-off-by: Will Deacon <will.deacon@arm.com>
2011-12-12ARM: lib: add call_with_stack function for safely changing stackWill Deacon
When disabling the MMU, it is necessary to take out a 1:1 identity map of the reset code so that it can safely be executed with and without the MMU active. To avoid the situation where the physical address of the reset code aliases with the virtual address of the active stack (which cannot be included in the 1:1 mapping), it is desirable to change to a new stack at a location which is less likely to alias. This code adds a new lib function, call_with_stack: void call_with_stack(void (*fn)(void *), void *arg, void *sp); which changes the stack to point at the sp parameter, before invoking fn(arg) with the new stack selected.
