| * Fix the VFP handling on the Feroceon CPUCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | This CPU generates synchronous VFP exceptions in a non-standard way - the FPEXC.EX bit set but without the FPSCR.IXE bit being set like in the VFP subarchitecture 1 or just the FPEXC.DEX bit like in VFP subarchitecture 2. The main problem is that the faulty instruction (which needs to be emulated in software) will be restarted several times (normally until a context switch disables the VFP). This patch ensures that the VFP exception is treated as synchronous. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Cc: Nicolas Pitre <nico@cam.org>
| * Add core support for ARMv6/v7 big-endianCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with ARMv6, the CPUs support the BE-8 variant of big-endian (byte-invariant). This patch adds the core support: - setting of the BE-8 mode via the CPSR.E register for both kernel and user threads - big-endian page table walking - REV used to rotate instructions read from memory during fault processing as they are still little-endian format - Kconfig and Makefile support for BE-8. The --be8 option must be passed to the final linking stage to convert the instructions to little-endian Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
| * RealView: Move the IRQ_* definitions out of the board-*.h filesCatalin Marinas2009-05-30
| | | | | | | | | | | | | | The IRQ_* macros need to be made visible via the mach/irqs.h file but without the additional macros defined in the board-*.h files. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
| * arm: Provide _sdata and __bss_stop in the vmlinux.lds.S fileCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | _sdata and __bss_stop are common symbols defined by many architectures and made available to the kernel via asm-generic/sections.h. Kmemleak uses these symbols when scanning the data sections. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
| * ARMv7: Document the PRRR and NMRR registers settingCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | This patch adds a comment to the proc-v7.S file for the setting of the PRRR and NMRR registers. It also sets the PRRR[13:12] bits to 0 (corresponding to the reserved TEX[0]CB encoding 110) to be consistent with the documentation. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
| * ARMv7: Enable the SWP instructionCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | | | | | The SWP instruction has been deprecated starting with the ARMv6 architecture. On ARMv7 processors with the multiprocessor extensions (like Cortex-A9), this instruction is disabled by default but it can be enabled by setting bit 10 in the System Control register. Note that setting this bit is safe even if the ARMv7 processor has the SWP instruction enabled by default. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
| * Clear the IT state when invoking a Thumb-2 signal handlerCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | If a process is interrupted during an If-Then block and a signal is invoked, the ITSTATE bits must be cleared otherwise the handler would not run correctly. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Cc: Joseph S. Myers <joseph@codesourcery.com>
| * ARMv7: Mark the PTWs inner WBWA on SMP and WB on UPTony Thompson2009-05-30
| | | | | | | | | | | | | | | | | | | | There are additional bits to set for the ARMv7 SMP extensions in the TTBR registers. The IRGN bits order is counter-intuitive but it allows software built for the ARMv7 base architecture to run on an implementation with the MP extensions.

| * Check whether the TLB operations need broadcasting on SMP systemsCatalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | | | | | ARMv7 SMP hardware can handle the TLB maintenance operations broadcasting in hardware so that the software can avoid the costly IPIs. This patch adds the necessary checks (the MMFR3 CPUID register) to avoid the broadcasting if already supported by the hardware. (this patch is based on the work done by Tony Thompson @ ARM) Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

The GPIO layer has had generic input and out defines called S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work for all S3C24XX GPIOs. Do the following replacements: S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT S3C2410_GP[A-Z][0-9]*_\INP => /S3C2410_GPIO_INPUT S3C2410_GPA[0-9]*_OUT => S3C2410_GPIO_OUTPUT to remove any usages of these and prepare the header for the removal of these.
