Subject: - build and use the list of the small initramfs
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=42450b1941db12165a1748bc41b5c1032105c31d;p=buildroot.git

- build and use the list of the small initramfs
  Overriding the use of the whole system (as does the initramfs target) is done
  on purpose.
