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.
For now this uses sudo and a compressed fallback file, like all the other bootstd tests. Once this series is in, the patch which moves this to use user-space tools will be cleaned up and re-submitted.
Signed-off-by: Simon Glass sjg@chromium.org
Here is the patch to avoid sudo and CI fallback:

We should not accept such binaries. This was just how xz was hacked (https://en.wikipedia.org/wiki/XZ_Utils_backdoor).
This binary wouldn't conform to the GPL 2.0 license either.
