Subject: [PATCH v14 1/5] firmware: Move firmware attributes class helper
Date: Tue, 1 Sep 2026 18:48:02 +0100 [thread overview]
Message-ID: <5682c2228fa4a784d3953664b56a06e0dd9ccdef.1788284852.git.sean@starlabs.systems> (raw)
In-Reply-To: <cover.1788284852.git.sean@starlabs.systems>
Move the firmware attributes class helper from drivers/platform/x86 to
drivers/firmware and expose its class declaration through a public Linux
header.
The helper is not x86-specific. Keeping it in drivers/firmware lets
coreboot firmware drivers use the standard firmware-attributes ABI without
living under platform/x86.
Replace the affected drivers' relative helper includes directly with the
new public header.
