Boot-tested on OMAP4 blaze board.

From ef436ef3cd34f5def720f3735900af36130ad37a Mon Sep 17 00:00:00 2001 From: Sebastien Jan <s-jan@ti.com> Date: Mon, 18 Oct 2010 18:00:55 +0200 Subject: [PATCH] wlan: register wlan device only on pandaboard BugLink: https://bugs.launchpad.net/bugs/665039 Registering the wlan device on blaze triggers the loading of user-space wlan drivers for 1271 chip. These user-space drivers are not compatible with the 1283 chip of the blaze and cause a kernel crash. The event is the same whatever the wlan controller, which prevents managing different wlan drivers in user-space. This patch registers the wlan device only on pandaboard. Long term, we would like to generate different events depending on the wlan controller.
