Subject[PATCH v8] FlexRM support in VFIO platform
Date
This patchset primarily adds Broadcom FlexRM reset module for
VFIO platform driver.

The patches are based on Linux-4.13-rc3 and can also be
found at flexrm-vfio-v8 branch of
https://github.com/Broadcom/arm64-linux.git

Changes since v7:
- Use "ret |= rc" instead of "ret = rc" in
vfio_platform_bcmflexrm_reset()

Changes since v6:
- Update the FlexRM ring flush sequence as suggested
by HW folks
- Shutdown all FlexRM ring anyway even if it fails on
any of the FlexRM rings
- Use dev_warn() instead of pr_warn()

Changes since v5:
- Make kconfig option VFIO_PLATFORM_BCMFLEXRM_RESET
default to ARCH_BCM_IPROC

Changes since v4:
- Use "--timeout" instead of "timeout--" in
vfio_platform_bcmflexrm_shutdown()

Changes since v3:
- Improve "depends on" for Kconfig option
VFIO_PLATFORM_BCMFLEXRM_RESET
- Fix typo in pr_warn() called by
vfio_platform_bcmflexrm_shutdown()
- Return error from vfio_platform_bcmflexrm_shutdown()
when FlexRM ring flush timeout happens

Changes since v2:
- Remove PATCH1 because fixing VFIO no-IOMMU mode is
a separate topic

Changes since v1:
- Remove iommu_present() check in vfio_iommu_group_get()
- Drop PATCH1-to-PATCH3 because IOMMU_CAP_BYPASS is not
required
- Move additional comments out of license header in
vfio_platform_bcmflexrm.c
