From 2868a5dff373f6d173ba2d060bbe910c38254cbf Mon Sep 17 00:00:00 2001 From: Ash Charles Date: Fri, 6 Jun 2014 11:27:28 -0700 Subject: [PATCH] omap: Don't enable GPMC CS0 with nothing attached If CONFIG_(NAND|NOR|ONENAND) is not defined, no configuration is set for GPMC on chip select #0---size is 0. In this case, the GPMC configuration should be reset but not enabled. Enabling causes the Gumstix DuoVero board to hang when entering Linux.
