Awesome! this looks great to me, but we probably should thrown
in a MODULE_ALIAS for g_NCR5380_mmio so that existing module
configurations keep working.

Can we make these #defines point to inline helper functions that avoid
the casting magic, e.g. something like
static inline void g_NCR5380_write(struct Scsi_Host *instance, u32 reg,
u8 value)
{
struct NCR5380_hostdata *host = shost_priv(instance);
iowrite8(value, host->iomem, host->offset + reg);
}
#define NCR5380_write(reg, value)
g_NCR5380_write(instance, reg, value)
