-Subject: [PATCH] MIPS: BCM47XX: Use mtd as an alternative way/API to get NVRAM
- content
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-NVRAM can be read using magic memory offset, but after all it's just a
-flash partition. On platforms where NVRAM isn't needed early we can get
-it using mtd subsystem.
