From a8dfb6462a033984b99fee4122fe0799a31f5bb4 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 7 Jan 2010 11:27:17 +0100 Subject: imx: define functions to configure chip selects in the WEIM This has the addional effect that the macros CSCR_U, CSCR_L and CSCR_A are not used anymore in mach-pcm038.c and mach-qong.c. These still use the deprecated IO_ADDRESS macro and shouldn't be used in new code.
