From daa7ce02513d2188fe6f5ff47ce5ef83eb7de739 Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Sun, 25 Oct 2015 22:16:47 +0100 Subject: MIPS: BCM47xx: Support on-SoC bus in SPROM reading function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To support (extract) SPROM on Broadcom ARM devices we should separate SPROM code and make it a separated module. We won't want to export bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard fallback function and then modify ssb to use it.
