falling back to UiApp?

[Laszlo Ersek <lersek@redhat.com>]

Hi Ray,

the UiApp application is added to the UEFI boot order automatically, but
it is not invoked automatically, even if BDS gives up and hangs with

  [Bds] Unable to boot!

For example, consider the following:
- no UEFI bootable application available anywhere in the system,
- ... not even for the default platform recovery option,
- no shell is built into the firmware image,
- but UiApp is available in the firmware image.

Is it possible to jump to UiApp in this case, rather than hanging with

  [Bds] Unable to boot!

?

Can (or should) platform code do something about this?

Or would this conflict with the UEFI spec either way?

Thank you,
Laszlo
