OMAP3 SDRC: add support for 2 SDRAM chip selects
Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2 SDRAM parts connected to the SDRC. This patch adds the following: - add a new argument of type omap_sdrc_params struct* to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params - adapted the OMAP boards files to the new prototype of omap2_init_common_hw - add the SDRC 2nd CS registers offsets defines - adapt the sram sleep code to configure the SDRC for the 2nd CS Note: If the 2nd param to omap2_init_common_hw is NULL, then the parameters are not programmed into the SDRC CS1 registers Tested on 3430 SDP and Beagleboard rev C2 and B5, with suspend/resume and frequency changes (cpufreq).
