From e4916e117a4fcd001a1be777e406ec1f98b75de4 Mon Sep 17 00:00:00 2001 From: Robert Nelson Date: Thu, 23 Sep 2010 18:22:48 -0700 Subject: [PATCH] omap: Beagle: only Cx boards use pin 23 for write protect system_rev comes from u-boot and is a constant 0x20, so Bx boards also fall in this 'if' and will get setup with the wrong gpio_wp pin. Switch to using the Beagle revision routine to correcly set pin 23 only for C1/2/3 and C4 Boards. Bx boards will then use the correct default pin setting.
