Patch Set 1:

Thank you for fetching my mistake. Commits should be for independent changes, so I factored the GRUB change out into [1] with you as author and your Signed-off-by line.

Please amend this commit to be just for TianoCore, and explain in the commit message, why the `all` target is gone. (The commit hash can be changed in the Kconfig menu, so it should be compatible.)
