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.
