From 7017fc54a5bccd95bebaf371bfa3098fcf84068a Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Tue, 21 Nov 2023 10:29:46 +0900 Subject: [PATCH] bootmeth: use efi_loader interfaces instead of bootefi command Now that efi_loader subsystem provides interfaces that are equivalent with bootefi command, we can replace command invocations with APIs.
