      ARM: Remove ARCH_HAS_CPUFREQ config option · 19682f72
      Stephen Boyd authored
      This config exists entirely to hide the cpufreq menu from the
      kernel configuration unless a platform has selected it. Nothing
      is actually built if this config is 'Y' and it just leads to more
      patches that add a select under a platform Kconfig so that some
      other CPUfreq option can be chosen. Let's remove the option so
      that we can always enable CPUfreq drivers on ARM platforms.

      ARM: integrator: fix section mismatch problem · e1318391
      Linus Walleij authored
      This addresses a section mismatch problem in the IM-PD1
      driver in the Integrator/AP.
      
      The IM-PD1 contains a VIC interrupt controller and therefore
      the driver calls vic_init_cascaded() which is marked __init as
      irqchips are simply not hot-pluggable and specifically the VIC
      is assumed to initiate only on boot.
      
      However the module driver model of the Integrator LM bus
      assumes that logic tile drivers can be probed at runtime. This
      is not really the case for IM-PD1: these tiles are detected at
      boot and they cannot be plugged into a running system. Before
      this patch it is of course possible to modprobe them later.
      
      By first forcing the IM-PD1 to bool we make sure this driver
      gets compiled into the kernel, and we know it will be probed
      only at boot time when the tiles are detected, so we can tag
      its probe function __init_refok as we know it won't be called
      after boot now, and the section mismatch problem goes away.
      
      As a side effect, sysfs binding from userspace becomes
      impossible, so we tag the driver to suppress the bind/unbind
      sysfs attributes.

      ARM: mvebu: DT: fix OpenBlocks AX3-4 RAM size · e47043ae

      The OpenBlocks AX3-4 has a non-DT bootloader.  It also comes with 1GB of

      ARM: samsung: make SAMSUNG_DMADEV optional · 27873b05
      Arnd Bergmann authored
      The only remaining driver using the samsung dmadev code is the broken
      samsung-ac97 sound driver. However, as found by Russell's autobuilder,
      the elaborate dependency chains around it cause problems with
      circular dependencies.
      
      This is an attempt to simplify those dependencies by making the
      SAMSUNG_DMADEV option user-selectable. I also try to keep the
      default settings for all related options unchanged, so we don't
      introduce any regressions against earlier testing on linux-next.
      
      In particular, all s3c64xx and s5p* platforms keep selecting the
      pl330 and pl08x drivers they require, but the select statement
      is now moved towards the main platform option, and it remains
      optional by unselecting CONFIG_DMADEVICES.

      remoteproc: da8xx: don't select CMA on no-MMU · 8c094524
      Arnd Bergmann authored
      We can only use CMA on systems that have an MMU, because of
      the requirement to use memory migration. NOMMU systems are
      rather constrained to start with, but it seems reasonable
      to assume that DMA allocations can still succeed in the
      constrained case for remoteproc on NOMMU, so this patch
      changes the da8xx implementation to not rely on CMA when
      the MMU is disabled.

      bus/arm-cci: add dependency on OF && CPU_V7 · 30b6f37d
      Arnd Bergmann authored
      The arm-cci code uses device tree helpers for initialization
      that don't work on kernels built without CONFIG_OF. Further,
      it contains an inline assembly in cci_enable_port_for_self()
      that uses ARMv7 instructions and fails to build when targetting
      other ARM instruction set versions.
      
      This works around both issues by limiting the scope of the
      Kconfig symbol to platforms that can actually build this driver
      cleanly.

      ARM: keystone requires ARM_PATCH_PHYS_VIRT · 13ee8955
      Arnd Bergmann authored
      The dynamic relocation that the keystone platform performs
      only works if we can pick the phys offset at boot time. It's
      possible that there is another solution for this, but this
      is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT
      are not portable across platforms, and I see no reason why
      anyone would run a kernel without ARM_PATCH_PHYS_VIRT on
      keystone.

      ARM: omap2: fix am43xx dependency on l2x0 cache · 2ad501cc
      Arnd Bergmann authored
      Commit d941f86f ("ARM: l2c: AM43x: add L2 cache support") enabled
      the L2 cache support for the am43xx SoC, but caused a build regression
      when the driver for that cache controller is disabled:
      
      arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
      :(.init.text+0xb20): undefined reference to `omap_l2_cache_init'
      
      This did not happen for OMAP4, which has the same call, but enables
      the l2x0 driver unconditionally. We could do the same thing for
      am43xx, but it seems better to allow turning it off and make the
      code work in either case.
      
      This adds an inline wrapper for omap_l2_cache_init for the disabled
      case, and removes the 'select' from OMAP4 so it becomes a user
      visible option.

        The main change here is to use the new dma-ranges parsing code that
        came in through Russell's ARM tree.  This allows the keystone platform
        to do cache-coherent DMA and to finally support all the available
        physical memory when LPAE is enabled.
      
        Aside from this, the keystone reset driver has been rewritten, and

      Linus Torvalds authored
      Pull powerpc updates from Ben Herrenschmidt:
       "Here is the bulk of the powerpc changes for this merge window.  It got
        a bit delayed in part because I wasn't paying attention, and in part
        because I discovered I had a core PCI change without a PCI maintainer
        ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
        probably improve it later and I didn't want to rebase to add his ack.
      
        There is going to be a bit more next week, essentially fixes that I
        still want to sort through and test.
      
        The biggest item this time is the support to build the ppc64 LE kernel
        with our new v2 ABI.  We previously supported v2 userspace but the
        kernel itself was a tougher nut to crack.  This is now sorted mostly
        thanks to Anton and Rusty.
      
        We also have a fairly big series from Cedric that add support for
        64-bit LE zImage boot wrapper.  This was made harder by the fact that
        traditionally our zImage wrapper was always 32-bit, but our new LE
        toolchains don't really support 32-bit anymore (it's somewhat there
        but not really "supported") so we didn't want to rely on it.  This
        meant more churn that just endian fixes.
      
        This brings some more LE bits as well, such as the ability to run in
        LE mode without a hypervisor (ie. under OPAL firmware) by doing the
        right OPAL call to reinitialize the CPU to take HV interrupts in the
        right mode and the usual pile of endian fixes.
      
        There's another series from Gavin adding EEH improvements (one day we
        *will* have a release with less than 20 EEH patches, I promise!).
      
        Another highlight is the support for the "Split core" functionality on
        P8 by Michael.  This allows a P8 core to be split into "sub cores" of
        4 threads which allows the subcores to run different guests under KVM
        (the HW still doesn't support a partition per thread).
      
        And then the usual misc bits and fixes ..."
