The efi_loader currently stops iterating over the available block devices stopping at the first device that fails. This may imply that no block device is found.
With the patch efi_loader only iterates over valid devices.
It is based on patch 06d592bf52f6 (dm: core: Add uclass_first/next_device_check()) which is currently in u-boot-dm.git.
For testing I used an odroid-c2 with a dts including &sd_emmc_a { status = "okay"; }; This device does not exist on the board and cannot be initialized.
Without the patch:
=> bootefi hello ## Starting EFI application at 01000000 ... WARNING: Invalid device tree, expect boot to fail mmc_init: -95, time 1806 Found 0 disks Hello, world! ## Application terminated, r = 0
With the patch:
=> bootefi hello ## Starting EFI application at 01000000 ... WARNING: Invalid device tree, expect boot to fail mmc_init: -95, time 1806 Scanning disk mmc@70000.blk... Scanning disk mmc@72000.blk...

This will be needed for the NanoPi K2 when importing the SDIO-enabled Linux .dts.
Simon, this patch requires your patches to be in tree first. What's your plan to move forward here?
It is applied to u-boot-dm/master but was too late for this release, which should be in a week.
Regards, Simon
