    OMAP3 SDRC: add support for 2 SDRAM chip selects · 58cda884
    Jean Pihet authored
    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).
