[U-Boot] [PATCH 1/1] efi_loader: bootmgr: print a message when loading from BootNext failed
From: AKASHI Takahiro takahiro.akashi@linaro.org
If a user defines BootNext but not BootOrder and loading from BootNext fails, you will see only a message like this: BootOrder not defined
This may confuse a user. Adding an error message will be helpful.

Adjust message for fallback from BootNext to BootOrder.
An example output looks like this:
=> bootefi bootmgr Loading from Boot0010 failed Loading from BootNext failed, falling back to BootOrder Loading from Boot0002 failed Loading from Boot0003 failed Loading from Boot0004 failed EFI boot manager: Cannot load any image

Why is the SoB line in the middle of the patch description?

How hard would it be to print the device path for the respective BootXXXX entries as well? Users usually don't think in boot entries.

Everything below was not in Takahiros patch.

The change is trivial. Output could look like
=> efidebug boot add 0001 label1 scsi 0:1 "\path1\file1.efi" => efidebug boot add 0002 label2 scsi 0:1 "\path2\file2.efi" => efidebug boot order 0001 0002 => bootefi bootmgr Loading from Boot0001 (/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Scsi(0,0)/HD(1,MBR,0x1bb2fc9c,0x800,0x3fffe)/\path1\file1.efi) failed Loading from Boot0002 (/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Scsi(0,0)/HD(1,MBR,0x1bb2fc9c,0x800,0x3fffe)/\path2\file2.efi) failed EFI boot manager: Cannot load any image =>
But as you see it does not fit into 80 character lines and the terminal might cut of the interesting part of the line. Failure may also depend on the command line parameters.
I think adding the label makes more sense.
Best regards

The SoB still comes at the end though :).

I agree. Maybe even only the label.
Booting label1... failed Booting label2... Welcome to grub!
