From f6eefaa4a08ec27c69485c2fc4db23247b84f8c9 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Tue, 1 May 2012 14:10:39 +0200
Subject: [PATCH v2 3/3] MTD: bcm63xxpart: use nvram for PSI size
Read out the SPI size from nvram instead of defaulting to 64K - some
vendors actually use values larger than the "max" value of 64.
