From 138173d4e826587da66c7d321da1a91283222536 Mon Sep 17 00:00:00 2001
From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= <zajec5@gmail.com>

Subject: [PATCH] MIPS: BCM47xx: Move NVRAM header to the include/linux/.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are two reasons for having this header in the common place:
1) Simplifying drivers that read NVRAM entries. We will be able to
safely call bcm47xx_nvram_* functions without #ifdef-s.
2) Getting NVRAM driver out of MIPS arch code. This is needed to support
BCM5301X arch which also requires this NVRAM driver. Patch for that
will follow once we get is reviewed.
