efi_loader: disk: iterate only over valid block devices
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:
