From 3f84622d7c7818077f5e6cf4b8a0d1b10dc65147 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 27 Nov 2010 19:26:32 +0100 Subject: [PATCH] SSB: Fix nvram_get on BCM47xx platform The nvram_get function was never in the mainline kernel, it only existed in an external OpenWrt patch. Use nvram_getenv function, which is in mainline and use an include instead of an extra function declaration. et0macaddr contains the mac address in text from like 00:11:22:33:44:55. We have to parse it before adding it into macaddr. nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h through the MIPS git tree and will be available soon. It will not build now without nvram_parse_macaddr, but it hasn't before either.
