From 4297c9869b3452860f1a2c588d43f9e62c701019 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Mon, 5 Feb 2007 20:01:15 -0600 Subject: [PATCH] [POWERPC] Maple: use mmio nvram Some systems supported by the maple platform (e.g. JS2x blades running SLOF) are able to use the mmio_nvram backend for reading and writing nvram. This is an improvement over the current situation -- no nvram access from userspace at all. Select MMIO_NVRAM for the maple platform. Initialize the mmio_nvram backend from maple setup code.
