- Serial output with no console. Run qemu with:

In lib/efi/efi_stub.c, efi_main() you set use_uart=true. Couldn't you do a similar thing in the app?
Instead of hard coding a specific UART it would be preferable both for the EFI stub as well as for the app to use the debug console defined by CONFIG_DEBUG_UART.
