In reworking the BLK usage in Kconfig, I found there's a few issues with EFI_LOADER=y and BLK=n. In general, we can easily say that lib/efi_loader/efi_file.c also should only be built with CONFIG_BLK. That however leaves the bootmgr code, eficonfig code and then parts of efi_device_path.c, efi_boottime.c and efi_setup.c which functionally depend on BLK. While these calls can be if'd out, I'm unsure if the result is usable. So rather than leave that buildable and imply that it is, I'm leaving that combination non-buildable and commenting that EFI_LOADER depends on BLK in the Kconfig currently.
EFI booting using only PXE or HTTP should be possible. But I admit we did not work on support for diskless devices, yet.
