• 756e46dba   ARM: EXYNOS: fix the hotplug for Cortex-A15 ... Browse Code »

  The sequence of cpu_enter_lowpower() for Cortex-A15 is
  different from the sequence for Cortex-A9. This patch
  implements cpu_enter_lowpower() for EXYNOS5 SoC which
  has Cortex-A15 cores.

  Basded on original patch has been submitted by Changhwan Youn

• 28e8e29c6   ARM: consolidate pen_release instead of having per platform definitions ... Browse Code »

  Almost each SMP platform defines pen_release to manage booting secondary
  CPUs. This of course clashes with the single zImage effort.

  Add the pen_release definition to the ARM SMP code, and remove all others.
  This should only be used by platforms which lack any kind of CPU power
  management...

  Avoid namespace conflicts with drivers over the CP15 definitions by
  moving CP15 related prototypes and definitions to a private header
  file.

• eb50439b9   ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMP ... Browse Code »

  It turns out that the logical CPU mapping is useful even when !CONFIG_SMP
  for manipulation of devices like interrupt and power controllers when
  running a UP kernel on a CPU other than 0. This can happen when kexecing
  a UP image from an SMP kernel.

  In the future, multi-cluster systems running AMP configurations will
  require something similar for mapping cluster IDs, so it makes sense to
  decouple this logic in preparation for this support.

• 830145796   ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos ... Browse Code »

  The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
  made for plaforms based on EXYNOS4 SoCs. But since upcoming
  Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
  codes in current mach-exynos4, one mach-exynos directory will
  be used for them.

  This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
  but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
  avoid changing in driver side.
