Subject: [PATCH 0/2] ArmPlatformPkg, ArmVirtPkg: discover NOR flash banks from DTB
Date: Fri, 16 Nov 2018 16:45:22 -0800 [thread overview]
Message-ID: <20181117004524.31851-1-ard.biesheuvel@linaro.org> (raw)
This series fixes an issue reported by Hongbo and Philippe, where
ArmVirtQemuKernel will crash on an attempt to access flash bank #0,
which is secure-only when running QEMU with support for EL3.
So let's switch to discovering the NOR flash banks from the device tree
instead. This requires some preparatory changes in the NOR flash driver
to avoid having to invent GUIDs on the fly.
Ard Biesheuvel (2):
ArmPlatformPkg/NorFlashDxe: use one GUID plus index to identify flash
banks
ArmVirtPkg/NorFlashQemuLib: discover NOR flash banks dynamically
