This patch moves S3C2410 stuff into mach-s3c24xx/ directory so that we can merge the s3c24 series' directories to the just one mach-s3c24xx/ directory. And this patch is including following. - re-ordered alphabetically by option text at Kconfig and Makefile - removed unused option, MACH_N35 - fixed duplcated option name, S3C2410_DMA to S3C24XX_DMA which is in plat-s3c24xx/ Cc: Ben Dooks <ben-linux@fluff.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443, and S3C2450 SoCs so that we can merge the mach-xxx directories and plat-s3c24xx dir. to just one mach-s3c24xx for them. I think this should be sent to upstream via samsung tree because this touches many samsung stuff.

Randomization of PIE load address is hard coded in binfmt_elf.c for X86 and ARM. Create a new Kconfig variable (CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead. Thus architecture specific policy is pushed out of the generic binfmt_elf.c and into the architecture Kconfig files. X86 and ARM Kconfigs are modified to select the new variable so there is no change in behavior. A follow on patch will select it for MIPS too.

This patch adds clk_prepare/clk_unprepare for mxs clock api by renaming the existing non-atomic clk_enable/clk_disable to clk_prepare/clk_unprepare and adding a pair of dummy clk_enable/clk_disable.

Activation conditions for a workaround should not be encoded in the workaround's direct dependencies if this makes otherwise reasonable configuration choices impossible. This patches uses the SMP/UP patching facilities instead to compile out the workaround if the configuration means that it is definitely not needed. This means that configs for buggy silicon can simply select ARM_ERRATA_751472, without preventing a UP kernel from being built or duplicatiing knowledge about when to activate the workaround. This seems the correct way to do things, because the erratum is a property of the silicon, irrespective of what the kernel config happens to be.

Activation conditions for a workaround should not be encoded in the workaround's direct dependencies if this makes otherwise reasonable configuration choices impossible. The workaround for erratum 720789 only affects a code path which is not active in UP kernels; hence it should be safe to turn on in UP kernels, without penalty. This patch simply removes the extra dependency on SMP from Kconfig. This means that configs for buggy silicon can simply select ARM_ERRATA_720789, without preventing a UP kernel from being built or duplicatiing knowledge about when to activate the workaround.

If running in the Normal World on a TrustZone-enabled SoC, Linux does not have complete control over the L2 cache controller configuration. The kernel cannot work reliably on such platforms without the l2x0 cache support code built in. This patch unconditionally enables l2x0 support for the Highbank SoC.

Making CACHE_L2X0 depend on (huge list of MACH_ and ARCH_ configs) is bothersome to maintain and likely to lead to merge conflicts. This patch moves the knowledge of which platforms have a L2x0 or PL310 cache controller to the individual machines. To enable this, a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow machines to indicate that they may have such a cache controller independently of each other. Boards/SoCs which cannot reliably operate without the L2 cache controller support will need to select CACHE_L2X0 directly from their own Kconfigs instead. This applies to some TrustZone-enabled boards where Linux runs in the Normal World, for example.

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: NWill Deacon <will.deacon@arm.com>

Commit 1b9f95f8 (ARM: prepare for removal of a bunch of <mach/memory.h> files) introduced CONFIG_PHYS_OFFSET but the Kconfig hex prompt did not provide a default value. This has the undesired side effect of breaking a reportedly used trick for updating defconfigs on the fly for routine buildtesting across all arch and all platforms, i.e. cp /path/to/somedefconfig .config ; yes "" | make oldconfig because the config system will endlessly loop until a valid address is provided. However we can't just pick a random default value since it is likely to be wrong for the majority of the boards as the right answer for this option is quite varied. So the fact that the config system insists on having a proper value be entered is actually a good thing. It turns out that only at91x40_defconfig has this problem because it has CONFIG_MMU=n. However, in the !MMU case, there is already a CONFIG_DRAM_BASE value that can be used here. So let's use that as a default in that case and suppress the redundant CONFIG_PHYS_OFFSET prompt. Eventually the DRAM_BASE config option could simply be replaced by PHYS_OFFSET directly, but that's a larger change better suited for later.

The Kconfig options for the PL310 errata workarounds do not use a consistent naming scheme for either the config option or the bool description. This patch tidies up the options by ensuring that the bool descriptions are prefixed with "PL310 errata:" and the config options are prefixed with PL310_ERRATA_, making it much clearer in menuconfig as to what the workarounds are for.

This patch implements a workaround for PL310 erratum 769419. On revisions of the PL310 prior to r3p2, the Store Buffer does not automatically drain. This can cause normal, non-cacheable writes to be retained when the memory system is idle, leading to suboptimal I/O performance for drivers using coherent DMA. This patch adds an optional wmb() call to the cpu_idle loop. On systems with an outer cache, this causes an explicit flush of the store buffer.
