Subject: [edk2-devel] [PATCH v1 edk2-platform 1/2] VExpressPkg: Add cache information related PCDs
Date: Fri, 5 Jul 2024 14:22:30 +0100 [thread overview]
Message-ID: <20240705132231.1574767-2-yeoreum.yun@arm.com> (raw)
In-Reply-To: <20240705132231.1574767-1-yeoreum.yun@arm.com>
From: "Levi Yun" <yeoreum.yun@arm.com>
Base FVP can configure cache information via model parameter.
But, there's no way to read model option dynamically in UEFI.
Add PCDs related to cache options which are correspondent to model option for
setting cache information at build time.
The default values are based on linux/arch/arm64/boot/dts/fvp_base_revc.dts
