-Subject: [PATCH 157/158] MIPS: BCM47XX: Move SPROM fallback code into sprom.c
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This is some general cleanup as well as preparing sprom.c to become a
-standalone driver. We will need this for bcm53xx ARM arch support.
