From d8cfb5037bfc875e6dc8e09e4caceb443c04ff6a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 26 Oct 2015 11:13:16 +0100 Subject: [PATCH 3/3] MIPS: BCM47xx: Fetch board info directly in callback function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This drops another symbol dependency between setup.c and sprom.c which will allow us to make SPROM code a separated module (and share it with ARM). Patch tested on Linksys WRT300N V1.
