From fc40d0191943fa995f5359b5c23aa7c3dea69d7b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 4 Nov 2010 12:02:35 +0100 Subject: [PATCH] ARM: imx: change the way flexcan devices are registered MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Group soc specific data in a global struct instead of repeating it for each call to imxXX_add_flexcanX. The structs holding the actual data are placed in .init.constdata and so don't do much harm. Compared to the previous approach this reduces code size to call imx_add_flexcan.
