[PATCH 01/18] efi: drop handling of 'boot_info' configuration table

From: Ard Biesheuvel
Date: Sun Feb 16 2020 - 13:24:05 EST


Some plumbing exists to handle a UEFI configuration table of type
BOOT_INFO but since we never match it to a GUID anywhere, we never
actually register such a table, or access it, for that matter. So
simply drop all mentions of it.
