[PATCH v10 00/11] enable HiP04 SoC

[Haojian Zhuang]

Changelog:
v10:
  * Move snoop filter code to be executed on secondary cores. And change
    it to assembly code since MMU isn't enabled at that time.
  * Rebase irq gic patch on latest gic patch.
  * Use global variable in irq gic patch.
  * Use global variable in vgic patch.
  * Drop debug uart patch since it's in another patch set.
  * Remove some ARCHs from multi_v7_lpae_defconfig.

v9:
  * Remove delay workaround in mcpm implementation.
  * Clean in gic.
  * Rename vgic_cpu_nr_lr to vgic_cpu_hw_cfg in vgic driver.
  * Always use high word of vgic_cpu_hw_cfg for GICH_APR offset. So the
    implementation of arm64 is also updated.
  * Drop "irq: gic: use mask field in GICC_IAR" patch since it's merged.

v7:
  * Remove hip04_smp_init_ops().
  * Remove CONFIG_ARCH_HIP04 in hisilicn.c since hip04_smp_init_ops() is
    removed.

v6:
  * Split HiP04 enabling patch into patches on document, mcpm & hiP04.
  * Move reset operation in HiP04 MCPM implementation.
  * Remove ARCH_MULTI_V7_NONLPAE & ARCH_MULTI_V7_LPAE according to olof's
    comment.

v5:
  * Add ARCH_MULTI_V7_NONLPAE to avoid change too much things in Kconfig.
  * Use memreserve in DTS.
  * Remove L2 reset operation in mcpm implementation.
  * Re-use nr_lr field to cover HIP04 GICH_APR implementation.
  * Add more comments.

v4:
  * Add multi_v7_lpae_defconfig.
  * Select CONFIG_ARCH_MULTI_V7_LPAE if CONFIG_ARCH_MULTI_V7 is selected.
  * Only ARMADA_XP is ARCH_MULTI_V7_LPAE, other ARMADA chips are ARCH_MULTI_V7.
  * Remove gich_lr0 variable since we can calculate offset of GICH_LR0 from
    GICH_APR.
  * Cleanup GIC driver to support HiP04 GIC.
  * Cleanup HiP04 mcpm implementation.

v3:
  * Replace CONFIG_ARCH_MULTI_V7 by CONFIG_ARCH_MULTI_V7_LPAE in some SoC.
  * Update MCPM code based on Dave's patch.
  * Remove MCPM node in DTS file. Use sysctrl & fabric node instead.
  * Move hardcoding on bootwrapper into DTS file.
  * Append the CONFIG_MCPM_QUAD_CLUSTER for HiP04.
  * Fix the return value from gic_get_cpumask() if it's used in standard gic.
  * Add the vgic support on HiP04 GIC.
  * Add virtualization support in HiP04 defconfig.

v2:
  * Append ARCH_MULTI_V7_LPAE configuration. Define ARCH_MULTI_V7 to only
    support non-LPAE platform.
  * Append document of DT supporting.
  * Append ARCH_HISI in hi3xxx_defconfig.
  * Enable errata 798181 for HiP04 SoC.
  * Add PMU support.
