Subject: [PATCH v2 0/3] arm64: Add HPE GSC platform support
Date: Mon, 23 Mar 2026 14:42:20 -0500 [thread overview]
Message-ID: <20260323194223.683487-1-nick.hawkins@hpe.com> (raw)
From: Nick Hawkins <nick.hawkins@hpe.com>
This series adds base platform support for the HPE GSC ARM64
BMC SoC used on HPE servers.
Patch 1 extends the existing hpe,gxp.yaml DT binding to cover GSC-based
boards (per DT maintainer guidance: one binding file per vendor).
Patch 2 adds the ARCH_HPE_GSC Kconfig entry to arm64/Kconfig.platforms.
Patch 3 adds the minimal SoC DTSI and DL340 Gen12 board DTS. The
full peripheral set (i3c, ethernet, etc.) will follow in a later
series after the relevant subsystem drivers are accepted upstream.
v1 was submitted as a single patch containing only the DT binding.
Based on review feedback from Krzysztof Kozlowski, this v2 expands to
a proper series covering the full base platform introduction.
Changes in v2:
- Drop hpe,gsc.yaml; extend existing hpe,gxp.yaml instead
(per Krzysztof Kozlowski review: one binding per vendor)
- Split into three patches: binding, Kconfig, and DTS
- Add gsc.dtsi + gsc-dl340gen12.dts
- Add ARCH_HPE_GSC to arm64/Kconfig.platforms

dt-bindings: arm: hpe,gxp: Add HPE GSC platform compatible
arm64: Kconfig: Add ARCH_HPE_GSC platform
arm64: dts: hpe: Add HPE GSC SoC and DL340 Gen12 board DTS
