This also fixes the following small issue: To allow dynamic support for multiple platforms, when those relevant macros are not defined for one specific platform, the default case will be: - SMC_DYNAMIC_BUS_CONFIG defined - and SMC_IRQ_FLAGS = IRQF_TRIGGER_RISING While if "irq_flags" is missing when defining the smc91x_platdata, usually as follows: static struct smc91x_platdata xxxx_smc91x_data = { .flags = SMC91X_USE_XXBIT, }; The lp->cfg.irq_flags will always be overriden by the above structure (due to a memcpy), thus rendering lp->cfg.irq_flags to be "0" always. (regardless of the default SMC_IRQ_FLAGS or IORESOURCE_IRQ_* flags) Fixes this by forcing to use IORESOURCE_IRQ_* flags if present, and make the only user of smc91x_platdata.irq_flags (renesas/migor) to use IORESOURCE_IRQ_*.

The tradeoff is, this can be specified in the smc91x platform data so that multiple boards support can be built in a single zImage.

A SMC91X_USE_DMA flag is added to the platform data to allow platform to choose its usage of DMA. Note this flag itself is so named to be generic enough (assuming other platforms can also use DMA). It keeps backward compatibility to set the SMC91X_USE_DMA flag if SMC_USE_PXA_DMA is still defined.
