2013-05-02Merge tag 'multiplatform-for-linus' of ↵Linus Torvalds1-1/+1
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform updates from Olof Johansson: "More multiplatform enablement for ARM platforms. The ones converted in this branch are: - bcm2835 - cns3xxx - sirf - nomadik - msx - spear - tegra - ux500 We're getting close to having most of them converted! One of the larger platforms remaining is Samsung Exynos, and there are a bunch of supporting patches in this merge window for it. There was a patch in this branch to a early version of multiplatform conversion, but it ended up being reverted due to need of more bake time. The revert commit is part of the branch since it would have required rebasing multiple dependent branches and they were stable by then" * tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (70 commits) mmc: sdhci-s3c: Fix operation on non-single image Samsung platforms clocksource: nomadik-mtu: fix up clocksource/timer Revert "ARM: exynos: enable multiplatform support" ARM: SPEAr13xx: Fix typo "ARCH_HAVE_CPUFREQ" ARM: exynos: enable multiplatform support rtc: s3c: make header file local mtd: onenand/samsung: make regs-onenand.h file local thermal/exynos: remove unnecessary header inclusions mmc: sdhci-s3c: remove platform dependencies ARM: samsung: move mfc device definition to s5p-dev-mfc.c ARM: exynos: move debug-macro.S to include/debug/ ARM: exynos: prepare for sparse IRQ ARM: exynos: introduce EXYNOS_ATAGS symbol ARM: tegra: build assembly files with -march=armv7-a ARM: Push selects for TWD/SCU into machine entries ARM: ux500: build hotplug.o for ARMv7-a ARM: ux500: move to multiplatform ARM: ux500: make remaining headers local ARM: ux500: make irqs.h local to platform ARM: ux500: get rid of <mach/[hardware|db8500-regs].h> ...
2013-04-08ARM: ux500: get rid of <mach/[hardware|db8500-regs].h>Linus Walleij1-1/+1
This removes <mach/hardware.h> and <mach/db8500-regs.h> from the Ux500, merging them into the local include "db8500-regs.h" in mach-ux500. There is some impact outside the ux500 machine, but most of it is dealt with in earlier patches. Contains portions of a clean-up patch from Arnd Bergmann.

2013-03-18ARM: mach-ux500: enable 128KB way L2 cache on DB8540Maxime Coquelin1-2/+2
DB8540 L2 was configured with 64KB way size, but it has 128KB as AP9540. Fix this by modifying ux500_l2x0_init() to use 128KB way size for all cpus in the x540 family.

2013-01-29ARM: ux500: de-globalize <mach/id.h>Linus Walleij1-1/+2
This removes the file <mach/id.h> from the global kernel include scope, making it a pure mach-ux500 detail. All ASIC specifics needed by drivers shall henceforth be passed from either platform data or the device tree. Cc: Rafael J.

2012-08-09ARM: ux500: reform Ux500 family namesLinus Walleij1-1/+1
Counting the U9540 and the new U8540 as a U8500 family member does not work. Instead, split the function in two: cpu_is_u8500_family() covering U8500 and U8520 cpu_is_ux540_family() covering U9540 and U8540 This works much better in practice. Update users to keep the same behaviour. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2012-05-02ARM: ux500: delete U5500 supportLinus Walleij1-3/+1
This platform has been obsoleted and was only available inside of ST-Ericsson, no users of this code are left in the world. This deletes the core U5500 support entirely in the same manner as the obsoleted U8500 silicon was previously deleted. The cpu_is_u5500() macros that can read out the CPU ID is left until the next kernel cycle, this makes it possible to merge deletion of dependent drivers without breakage. This also has the upside of removing the mailbox driver which was our only driver that was outside the drivers/* hiearchy, now the machine directory only handles machines and nothing else.

2012-05-02ARM: ux500: core U9540 supportLinus Walleij1-3/+13
This adds support for the U9540 variant of the U8500 series. This is an application processor without internal modem. This is the most basic part with ASIC ID, CPU-related fixes, IRQ list, register ranges, timer, UART, and L2 cache setup. This is based on a patch by Michel Jaouen which was rewritten to fit with the latest 3.3 kernel. ChangeLog v1->v2: deleted the irqs-db9540.h file since we expect to migrate to using Device Tree for getting the IRQs to devices. ChangeLog v2->v3: introduced a fixed virtual offset for the ROM as suggested by Arnd Bergmann.

2012-01-20mach-ux500: do not override outer.inv_allsrinidhi kasagar1-41/+7
Invalidating outer cache without disabling it is a big nono, and so, remove the machine specific outer.inv_all And at the same time it does not prevent us overriding outer.disable as we do not have any such secure SMI to handle the same while kexec disables the outer cache.

Following mach-imx we break out the l2x0 handling into its own file, avoiding some ifdefs. Also remove unnecessary creation of local pointers when there is already one file-local readily available.
