bzImage under x86_64 UEFI app mode.

Hi. I'm trying the new UEFI-app mode where I rely on EFI services to give me access to things like block devices etc. I'm currently using 2022.04-rc1. So far so good. I can start U-boot and the efi block device works just fine. But I'm not succeeding in booting a regular bzImage. This kernel (5.1

Hints on how to use efi_driver/efi_block_device.c

I was hoping that U-boot would detect BLOCK_IO devices provided by UEFI automatically. But I can't see anything attached under lsblk or find some other information about this. For example, Barebox works just fine on both Virtualbox and real hardware in this regard. Barebox does not have an emm
