qemu 4.0.0 on aarch64: uefi firmware oversize
I'd like to enable uefi in my virtual machine, however qemu is always showing the same error: qemu-system-aarch64: Initialization of device cfi.pflash01 failed: device requires 67108864 bytes, block backend provides 786432 bytes
It's clearly impossible to fit a uefi firmware into 786432 bytes.
Environment: qemu-system-aarch64 with kvm on an amlogic s905d aarch64 dev board, running archlinuxarm, qemu in the repository is compiled with https://download.qemu.org/qemu-4.0.0.tar.xz
(My AAVMF_CODE.fd and AAVMF_VARS.fd are extracted from debian package qemu-efi-aarch64 0~20181115.85588389-3)
Below is my libvirt log.
