From f6f57a46435d7253a52a1a07a58183678ad266a0 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 21 Aug 2018 00:29:51 +0900 Subject: initramfs: move gen_initramfs_list.sh from scripts/ to usr/ scripts/gen_initramfs_list.sh is only invoked from usr/Makefile. Move it so that all tools to create initramfs are self-contained in the usr/ directory.
