From 9fb97412c3be5d0d1dd0e9d7c5268469e4c942aa Mon Sep 17 00:00:00 2001 From: Jean Pihet Date: Fri, 24 Jul 2009 19:43:25 -0600 Subject: OMAP3: Setup MUX settings for SDRC CKE signals This patches ensures the MUX settings are correct for the SDRC CKE signals to SDRAM. This allows the self-refresh to work when 2 chip-selects are in use. A warning is thrown away in case the initial muxing is incorrect, in order to track faulty or old-dated bootloaders. Note: The CONFIG_OMAP_MUX and CONFIG_OMAP_MUX_WARNINGS options must be enabled for the mux code to have effect.
