From 47a348614492987ef307aad299c09163344e4eaf Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Mon, 2 Aug 2010 23:56:22 +0200 Subject: MIPS: BCM47xx: Fix nvram_getenv return value. Nvram_getenv should behave like cfe_getenv. cfe_getenv returns 0 on success and -9 if the value was not found. If the input was wrong -8 will be returned by cfe_getenv. Change nvram_getenv to do the same.
