When running the EFI app via QEMU with EDK II using
cp /usr/share/OVMF/OVMF_VARS_4M.fd .
qemu-system-x86_64 -enable-kvm -m 2048 \
-machine q35,smm=on \
-drive
if=pflash,format=raw,readonly=on,file=/usr/share/OVMF/OVMF_CODE_4M.fd \
-drive if=pflash,format=raw,file=OVMF_VARS_4M.fd \
-hda disk
every character printed to the console by the U-Boot app appears twice. See
https://gist.github.com/xypron/7214e785c7d73104f8541bcac363a192 .
The reason is that environment variable stdout has serial,vidconsole as
value. This is defined by board/efi/efi-x86_app/efi-x86_app.env including
include/env/x86.env.
Provide a proper efi-x86_app.env file which does not use vidconsole.
