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.
Changes since v1:
- split ArmPlatformPkg for clarity
- move DT node status check into FdtClientDxe where it belongs
- use correct UINT32* type for DT property values, and be pedantic about
their potential misalignment when casting to UINT64*
- add patch to remove the 'Guid' member from NOR_FLASH_DESCRIPTION
- add some acks
Ard Biesheuvel (5):
ArmPlatformPkg/NorFlashDxe: prepare for devicepath format change
ArmPlatformPkg/NorFlashDxe: use one GUID plus index to identify flash
banks
ArmVirtPkg/FdtClientDxe: take DT node 'status' properties into account
ArmVirtPkg/NorFlashQemuLib: discover NOR flash banks dynamically
ArmPlatformPkg/NorFlashPlatformLib: remove unused Guid member from
struct
