2011-10-04ARM: EXYNOS4: Add support SMDK4412 BoardChanghwan Youn
SMDK4412 board is same as a SMDK4212 board except that it has EXYNOS4412 SoC, thus it can share machine code with SMDK4212. This patch renames mach-smdk4212.c to mach-smdk4x12.c to support both SMDK4212 and SMDK4412 board with one machine file.

2011-10-04ARM: EXYNOS4: Add MCT support for EXYNOS4412Changhwan Youn
Current MCT implementation only provide 2 event timers, thus cannot support EXYNOS4412 which has 4 CPU cores. This patch fixes MCT implementation to support SoCs with 4 cores. Signed-off-by: Changhwan Youn <chaos.youn@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-10-04ARM: EXYNOS4: Add functions for gic interrupt handlingChanghwan Youn
This patch adds two functions for gic interrupt handling. 1. Add interrupt handling of 4 cores. 2. Dynamically set gic bank offset according to the type of soc. Gic bank offset of EXYNOS4412 is 0x4000 while the offset of EXYNOS4210 and EXYNOS4212 is 0x8000. This patch is necessary because EXYNOS4 socs cannot support GIC register banking as described in commit aab74d3e75364.

2011-10-01ARM: OC_ETM should not select ARM_AMBAArnd Bergmann
The CONFIG_ARM_AMBA symbol is selected by the platforms that support AMBA, and the other platforms (e.g. orion) might not be able to build that code at all when they do not support the clk API. Instead, make sure that OC_ETM is only built on platforms that do support the amba subsystem already. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: pci: always export pcibios_bus_to_resourceArnd Bergmann
Some PCI drivers call pcibios_bus_to_resource directly, but it is only exported when CONFIG_HOTPLUG is set, because it was initially mean for pccard support. Moving the export out of the #ifdef lets us avoid these build errors: ERROR: "pcibios_bus_to_resource" [drivers/video/vt8623fb.ko] undefined! ERROR: "pcibios_bus_to_resource" [drivers/video/arkfb.ko] undefined! ERROR: "pcibios_bus_to_resource" [drivers/video/s3fb.ko] undefined! Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2011-10-01ARM: limit CONFIG_HAVE_IDE to platforms that doArnd Bergmann
Support for IDE drivers should not be automatic, since most platforms cannot actually support any IDE low-level drivers. This partly reverts 2064c946e "ARM: always select HAVE_IDE" to set this symbol only when either a PC-style bus (PCI, ISA, PCMCIA) is enabled or a platform is used that is known to have an existing driver in drivers/ide. New platforms should not need this option and just use CONFIG_ATA with drivers/ata/. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: pm: let platforms select cpu_suspend supportArnd Bergmann
Support for the cpu_suspend functions is only built-in when CONFIG_PM_SLEEP is enabled, but omap3/4, exynos4 and pxa always call cpu_suspend when CONFIG_PM is enabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: vfp: use -mfloat-abi=soft to build vfpArnd Bergmann
Distros are starting to ship with toolchains defaulting to hardfloat. Using such a compiler to build the kernel fails in the VFP directory with arch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP Adding -mfloat-abi=soft to the gcc command line fixes this.

2011-10-01ARM: allow building alignment.c without PROC_FSArnd Bergmann
The two functions cpu_is_v6_unaligned and safe_usermode are only defined when CONFIG_PROC_FS is enabled, but are used outside of the #ifdef. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Dave Martin <dave.martin@linaro.org>
2011-10-01ARM: always use ARM_UNWIND for thumb2 kernelsArnd Bergmann
Thumb2 kernels cannot be built with frame pointers, but can use the ARM_UNWIND feature for unwinding instead. This makes sure that all features that rely on unwinding includeing CONFIG_LATENCYTOP and FAULT_INJECTION_STACKTRACE_FILTER do not enable frame pointers when the unwinder is already selected, and we always build with the unwinder when we want a thumb2 kernel, to make sure we do not get the frame pointers instead. A different option would be to redefine the CONFIG_FRAME_POINTERS option on ARM to mean builing with either frame pointers or the unwinder, and then select which one to use based on the CPU architecture or another user option. That would still allow building thumb2 kernels without the unwinder but would also be more confusing. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
