[edk2-devel] [PATCH 00/11] ArmVirtPkg: introduce VirtNorFlashDxe

Create a new driver VirtNorFlashDxe that targets QEMU and KvmTool's NOR
flash emulation specifically, and retire the ArmPlatformPkg one.
This permits new virt implementations to wire up QEMU's NOR flash
emulation without having to rely on ARM specific packages. It also
permits us to implement some tweaks to work around some rough
performance edges of KVM memslot backed NOR flash.
