From fc28c39f0ef59bfb649ddfd633275be8e45c0f9c Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 17 Jul 2009 14:39:23 +0200 Subject: mtd: maps: add mtd-ram support to physmap_of MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use physmap_of to access RAMs as mtd and add documenation for it. This approach is a lot less intrusive as adding an of-wrapper around plat-ram.c. As most extensions of plat-ram.c (e.g. custom map-functions) can't be mapped to the device tree anyhow, extending physmap_of seems to be the cleanest approach. Tested with a phyCORE-MPC5121e.
