From 4ef806096bdbbe9e77c29c17c3ed636d00d6d6f3 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 17 Oct 2022 17:14:41 +0200 Subject: [PATCH] arm64: efi: Move efi-entry.S into the libstub source directory We will be sharing efi-entry.S with the zboot decompressor build, which does not link against vmlinux directly. So move it into the libstub source directory so we can include in the libstub static library.
