Subject: efi: Drop handling of 'boot_info' configuration table
X-Git-Tag: v5.10.7~2527^2~36^2~38
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=50d53c58dd77d3b0b6a5afe391eaac3722fc3153;p=platform%2Fkernel%2Flinux-rpi.git

efi: Drop handling of 'boot_info' configuration table

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.
