From d085eea16c05e5fecf258fc254059e9bc1e6db91 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Sat, 23 Mar 2013 14:07:49 +0100 Subject: [PATCH] mtd: bcm63xxpart: use nvram for PSI size MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Read out the SPI size from nvram instead of defaulting to 64KiB — some vendors actually use values larger than the "max" value of 64.
