Michael Tokarev: I find your reply to be disrespectful.
I can and did use search engines. My results indicated that more recent versions of QEMU do support 64MiB flash in the virt machine type. Maybe this older version from stable doesn't support it, or maybe my invocation is wrong. However, I did try multiple types of invocation to get the size of the pflash to be 64MiB, which did not work.
If there is a version discrepancy between this version of qemu-system-aarch64 and qemu-efi-aarch64, then that is a bug because both of these packages came from Debian Stable. They should work together.
At the very least, there is a documentation bug, because there is no explanation for how to invoke qemu with this EFI image. In fact, my invocation already shows that I know how to use a search engine, because using a search engine is the only way to figure out how to use this thing.
