Subject: [PATCH 01/11] OvmfPkg: clone NorFlashPlatformLib into VirtNorFlashPlatformLib
Date: Mon, 24 Oct 2022 19:01:12 +0200 [thread overview]
Message-ID: <20221024170122.594577-2-ardb@kernel.org> (raw)
In-Reply-To: <20221024170122.594577-1-ardb@kernel.org>
Create a new library class in Ovmf that duplicates the existing
NorFlashPlatformLib, but which will be tied to the VirtNorFlashDxe
driver that will be introduced in a subsequent patch. This allows us to
retire the original from ArmPlatformPkg.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
