One more thing I noticed recently is that we still have some
hardcoded configuration in the driver:

  #ifdef CONFIG_ARCH_PXA
    #define SMC_USE_PXA_DMA       1
    #define SMC_USE_16BIT         0
    #define SMC_USE_32BIT         1
    #define SMC_IRQ_SENSE         IRQF_TRIGGER_FALLING
  #elif defined(CONFIG_SH_MAGIC_PANEL_R2)
    #define SMC_USE_16BIT         0
    #define SMC_USE_32BIT         1
    #define SMC_IRQ_SENSE         IRQF_TRIGGER_LOW
  #elif defined(CONFIG_ARCH_OMAP3)
    #define SMC_USE_16BIT         0
    #define SMC_USE_32BIT         1
    #define SMC_IRQ_SENSE         IRQF_TRIGGER_LOW
    #define SMC_MEM_RESERVED      1
  #elif defined(CONFIG_ARCH_OMAP2)
    #define SMC_USE_16BIT         0
    #define SMC_USE_32BIT         1
    #define SMC_IRQ_SENSE         IRQF_TRIGGER_LOW
    #define SMC_MEM_RESERVED      1
  #else
  /*
   * Default configuration
   */
  
  #define SMC_DYNAMIC_BUS_CONFIG
  #endif

and I suspect we have to convert the OMAP2/OMAP3 portion here to use
dynamic configuration, otherwise things may go wrong in a multiplatform
kernel.
