Series efi: Add a test for EFI bootmeth | expand

Commit Message

Simon Glass Sept. 2, 2024, 1:18 a.m. UTC
Create a new disk for use with tests, which contains the new 'testapp'
EFI app specifically intended for testing the EFI loader.

Attach it to the USB device, since most testing is currently done with
mmc.

Initially this image will be used to test the EFI bootmeth.

Fix a stale comment in prep_mmc_bootdev() while we are here.

This reminds me of the xy hack. We should not add binary files. Please,
create it on the fly.
