[v3][PATCH 0/8] arm64: defconfig: enable several options useful for ARM64 server platforms

[Timur Tabi]

ACPI-based ARM64 server platforms based, like the Qualcomm Datacenter
Technologies QDF2400, need several features and drivers enabled for
full functionality.  This patchset enables many of those features.

Timur Tabi (8):
  arm64: defconfig: enable ACPI_CPPC_CPUFREQ
  arm64: defconfig: enable BLK_DEV_NVME
  arm64: defconfig: enable EFI_CAPSULE_LOADER
  arm64: defconfig: enable support for PCIe hotplug
  arm64: defconfig: enable APEI and GHES features
  arm64: defconfig: enable EDAC options
  arm64: defconfig: enable QCOM_L2_PMU and QCOM_L3_PMU
  [v2] arm64: defconfig: enable Qualcomm Technologies EMAC and some PHY

[PATCH 2/8] arm64: defconfig: enable BLK_DEV_NVME

[Timur Tabi]

NVME is non-volatile storage media attached via PCIe. NVME devices
typically have much higher potential throughput than other block
devices, like SATA, NVME is a must-have requirement for ARM64 based
servers.

[PATCH 3/8] arm64: defconfig: enable EFI_CAPSULE_LOADER

[Timur Tabi]

CONFIG_EFI_CAPSULE_LOADER allows the user to update the EFI firmware,
which is useful on ARM64 server platforms.

[PATCH 4/8] arm64: defconfig: enable support for PCIe hotplug

[Timur Tabi]

Some ARM64 server systems support PCIe hotplug, so enable the options
for that.

[PATCH 5/8] arm64: defconfig: enable APEI and GHES features

[Timur Tabi]

ARM64 server platforms can support ACPI Platform Error Interface (APEI)
and Generic Hardware Error Source (GHES) features, so enable them.

Platforms which support the firmware-first RAS error reporting model
require APEI and GHES functionality for the OS to receive and report
error records provided by the platform.

PCIe AER functionality is required for PCIe AER errors to be properly
reported and recovered from.

[PATCH 8/8] [v2] arm64: defconfig: enable Qualcomm Technologies EMAC and some PHY drivers

[Timur Tabi]

The EMAC is present on Qualcomm Technologies' server and some mobile
chips, and is used as the primary Ethernet interface.

Systems that have these SOCs typically have an Atheros 803x or
Marvell 88e1111 PHY in them, so enable those drivers too.

Applied all eight, one of them with slight context changes.

Thanks!
