Subject: [PATCH 01/18] efi: drop handling of 'boot_info' configuration table
Date:   Sun, 16 Feb 2020 19:23:17 +0100
Message-Id: <20200216182334.8121-2-ardb@kernel.org>
In-Reply-To: <20200216182334.8121-1-ardb@kernel.org>
References: <20200216182334.8121-1-ardb@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
