      ARM: moxart: fix CPU selection · f8afae40
      Arnd Bergmann authored
      Moxart uses an FA526 CPU core, which is ARMv4 based, not ARMv4T.
      Before moxart, we had no CONFIG_MULTI_V4 option, since no ARMv4 platform
      was enabled for multiplatform. This now adds the missing option, which
      will give us slightly more efficient code on pure moxart kernels,
      because we can build a pure FA526 kernel now rather than a combined
      FA526+ARM920T kernel that we used to.

      In a combined ARMv6/v7 kernel, we cannot use the
      movt/movw instructions to load an immediate, as they
      are not valid on ARMv6.
      
      This changes the file to use an indirect load instead,

      ARM: exynos: fix l2x0 saved regs handling · 39378e41
      Arnd Bergmann authored
      The exynos4_l2x0_cache_init function tries to flush the data cache
      for the location of the saved l2x0 registers and pass the physical
      address to the s5p-sleep implementation.
      
      However, the s5p-sleep code is optional, and if it is disabled,
      we get a linker error here when the l2x0_regs_phys variable does
      not exist.
      
      To solve this, use a compile-time conditional to drop this code
      if we don't want it.

      ARM: s5p64x0: fix building with only one soc type · 4f579c03
      Arnd Bergmann authored
      The s5p64x0 platform supports two distinct SoCs, s5p6440 and s5p6450,
      and in the normal configuration, both are enabled. However if we build
      a kernel that only enables one of the two, the #ifdef logic in common.c
      breaks down, as some of the functions declared in the header are defined
      to NULL using the preprocessor but then defined anyway.
      
      This patch cleans up the mess and ensures that each function has either
      exactly one C declaration and one matching C definition, or we have
      a NULL defined function pointer but no C definition.

      The SAAR and TAVOREVB machines try to call functions from
      the PXAFB frame buffer driver from their platform code,
      which only works if that driver is built-in.
      
      This patch ensures that both the generic frame buffer
      code and the specific pxafb driver are always enabled
      when we build a kernel for one of the two boards.

      ARM: pxa: don't "select" SMC91X on MACH_XCEP · a0ad0fdb
      Arnd Bergmann authored
      We normally don't hard-enable Kconfig options just because
      a board contains a specific piece of hardware. In this case,
      selecting SMC91X causes a build error, if we don't also enable
      basic network device driver support.
      
      Since the platform has no direct dependency on this driver
      at link time, we can just remove the 'select' statement.

      ARM: orion5x: make dns323 independent of PHY support · 32ff4971
      Arnd Bergmann authored
      The D-Link DNS-323 machine tries to unconditionally select CONFIG_PHYLIB,
      but that has other dependencies that might not necessarily be enabled,
      causing random build errors.
      
      To work around this, this patch removes the 'select' statement and
      instead uses a compile-time check to skip the phy_register_fixup_for_uid()
      call if PHYLIB is not available in the kernel.

      ARM: mvebu: add missing header · 9e128041
      Arnd Bergmann authored
      The definition for SIGBUS may not be visible without including
      linux/signal.h, as I found during randconfig testing.
      
      Adding an explicit include is certainly the right thing to do.

      ARM: omap1: don't rely on tps65010 · 0b31c53b
      Arnd Bergmann authored
      The code for h2 and osk implicitly assumes that the tps65010
      driver is built-in, in order to perform the initial regulator
      setup.
      
      This is fine for most real uses, but it does get into the way
      of build testing with 'make randconfig', since we don't want
      platforms to implicitly select device drivers and subsystems
      such as I2C.
      
      This patch by contrast changes the board files to not call
      into the tps65010 driver when that is not built-in, allowing
      us to build all configurations including some that will not
      work properly on this hardware.
